All these type "chips" are a fraud. The only thing they will do is lighten your pocket.

ouch!!

they have 100% refund and state 4-7 mpg.

gotta think they'd not be in business if they could not back it up in some way...

recommendations then for better mpg???

All of these "chips" are bogus. Most if not all are used to modify your MAF/MAP readings to either lean out your fuel trim or fatten it up. Either way it isn't exactly a safe thing to do. If it was, the manufacturer would have done that in the beginning to raise their mpg ratings for the CAFE crap.

If you are really into mpg with your 4x4 truck, then you should consider switching to full synthetics. Maybe remove your front halfshafts when you know you will not be using 4x4. Heck, maybe just pick up some kind of beater vehicle (old civic) that will get you 34mpg but will not hold up in an accident.

In the end, you have to pay to play so if you want a truck, you pay for that. If you want a mpg friendly vehicle, you get something that is bland. Not exactly saying get a prius like others would say but something along those lines.

I have an "econo" map from Uprev. I trust Uprev to get the tuning right such that my engine is not in danger (running lean). That said, I seem to get as good or better mileage using my 88 octane performance map than I do from the "econo" map.

So I don't see other tuners being able to do much better.

thanks for the replys/input...

but let me clear up some things.

i was sold this 'flex' vehicle by the dealer - that it would get "14-18 mpg all day long".
i was not privy to the fact that 'E85' would SUCK for mileage...learned the hardway. on a christmas road trip: cruise set at 70 mph from st. paul to fargo nd, i got 9.6 mpg. that is just plain wrong; however that was on flex..... and into north dakota, it is only a 10% mix - so it was 89 w/ 10%. from fargo to the destination and then return trip home was a 9, 11, 13 mpg...

dealer was only slightly concerned and said to 'keep an eye' on it and keep him informed. NOW, i have non-factory spec tires on (what WAS on it was even bigger) - so my mph, tranny shift and speedo are not correct...

all that said, i am trying to get the 'best' fuel mileage possible (at least in the range i was told) if not better. in the future (perhaps this summer/fall) a bed cover.

back to the 'chips': i have been emailing back and forth w/ a guy from gforce and he said actual for the titan is a 35 hp and 3-4 mpg increase. in reading the 'tech' on it, it is basically doing the 2* timing advance and optimizing for best efficiency. i see no difference in this vs. the 2* timing advance mod.

short of selling these 18" rims/tires and going back to factories, i am looking at all other options. suggestions welcome.

sorry for the long rambling.

1. Slow down - I can get 22 mpg on the highway at 65 mph. Crank it up to 75 and my mpg drops to about 18. Note that this in ONLY in the summer and on gas outside the Denver area. Not 100% sure why Denver area gas sucks, but in the winter it has more ethanol in it for sure.
2. Check the viscosity in your engine oil - spec is 5w-30. Put in 10w-40 and it is likely to affect your mileage. I run synthetic 0w-30 all year long.

There is no way that item will give a 35 HP gain - period. If they tell you that they are lying.
Oversize tires kill the mileage on the Titan.

hrtkd: slow down....everyone in the world has been told to drive the speed limit...now you tell me i have to drive 5 mph under to gain the best mileage...(sweet spot if you will)...that is gonna be hard to do when you have been driving for the last 24 years...
p.s. the gm at the dealer told me the same thing!!!

as for the oil: i would love to switch it, but the dealer does free oil changes as part of what they offer when buy a vehicle...kind of hard to pass that up.

scr38: 35 and 3-4 is what they say is typical of titan outcomes.. their reputation, product testing and testimonials gotta say otherwise... jmtc opinion and i appreciate yours too.

i agree that bigger tires affect mileage but i also learned that one the hard way as the titan is not able to re-program the computer as all my other vehicles were able to do... but to go from a 245 to a 265 tire can't affect it THAT bad, non the less it does affect it.

i think i will do a little more research and a couple of more tanks (without E85) and try and find some hiway travel at 65 to see what it get, then go back to dealer to complain.

anyone else have ideas??!!

My 05 2WD with Big Tow, 2* advance averages 14 with regular. 18 highway. On the factory 18's. Flex just plain drinks to much fuel. Unless you can get it super cheap. But here in Vegas it is only about twenty cents cheaper. Not enough in my book.

car companies make cars for the masses,,, thats why performance parts, or performance cars cost more, they are better than OEM, programmers, do work, they are not a scam, except, you get what you pay for, as with any product.

I'm gonna jump in on this. for starters, free oil changes aren't always a good thing. they could just be throwing in the cheapest oil they can find and that is NOT helping your mileage or performance. my wife got free car washes at her dealer, but the car always came back dirty. just an example. dealers aren't looking out for your best interest. they just wanna sell you a car. bottom line.

I can set up a site with ease that can say a bag of cheetos can be used to stop radiator leaks, does it make it true? you can call me, and i'll say......yeah it works. i can just as easily have some friends co-sign on the idea, using some bogus name, just for the heck of it. I think it is not a good idea to try such things without some sort of out side proof.

there are many well versed members when it comes to the Titan on this forum, Mighty titan and Titan talk, i can almost assure you that they will say the same thing.

but if your still not convinced, just buy one and tell us how it turns out.
BTW, E-bay offers the same kind of chip increase. check there first and see if you find this other brand your thinking about. just know that most members here try to look out for each other. we don't want to see you mess up your truck by trying to take a shortcut or something. there are certain things you can and can't do to the beast. and the quick chip install has not been proven on any of the popular forums to be helpful.

you seem to want to listen to salesman for the chip rather then people who are trying to save you your money. When CAI first came out for the titan they too were claiming 35 HP gains, its all hype. You are entitled to spend your money anyway you please, but I promise you that you will be disappointed in the chip.

You mentioned you changed wheels and tires. If the aftermarket wheels are heavy, or if the tires are heavier then stock with a beefier higher rolling resistance tread, you are loosing mpg. Unsprung added weight is one of the biggest fuel robbers you can do to a vehicle. A tanaue or bed cover would help mpg, and if your really interested in mileage, you need to keep the speed under 65 mph.

Ask yourself this also, if this chip worked so great, why would not all of the Titan enthusiasts who are willing to spend large amounts of money for performance gains not have this chip?

GUYS: first off thanks for the input. you both make good points. but let me clarify some things....

1. i am not 'listening' to the chip salesman....yes he is just a salesman. rather i was just trying to 'stand up' for their side of the story - as reputation and testimonials go.

2. my wheels stayed the same - my tires changed. according to the factory sticker on the door, the factory sticker says 245/65/17. what was on truck that i replaced was contitracs 275/70/18 load range E. what i put on was a passenger tire 265/70/18 (no E)with a little more aggressive tread.

3. adding a bed cover is on the short list (wife likes idea too) - which would help mpg

4. i just filled up last nite and the last tank got 11.1 mpg....SOMETHING just does not add up. this thing gets worse mpg than the wifes kia van w/ 117k on the clock. i was able to do some long (and by long i mean freeway travel other than in town stop light driving) and i set the cruise at 65. the last 3 tanks fulls have been on 89 octane too.

i am at a loss and getting frustrated to be honest. when the dealer sells you on a vehicle that will get 14-18 all day long (and from that i was hoping to GAIN in mpg) and 'gives you the impression' that FLEX is a good thing (i knew no better - my bad) and things turn out this way - it is frustrating. HAD i known i would not be able to adjust the computer for different tires, i would not have gotten what i did and quite possibly passed on this truck...but i made the bed now i have to lay in it.....to top it off, gas prices are rising and it just went up 10 cents overnite so i got to pay $3.19 here yesterday......and it looks as if it is only gonna get worse over the next few months - to over $4 by summer.

SO, time to cheer up and get me cheered up.....
what can i do (changing tires not an option) to help my situation...and driving 65 looks like it is my best friend for awhile - to see what that does for me...

thanks guys, i appreciate your candor and honesty

Mileage still...

So your salesman told you it'd get 14-18 all day and you're not. Please read the following to gain a little perspective...

Chevy, GMC, and Dodge all claim they get better gas mileage and maybe they do. However, I did the math. I average 14 mpg driving 80 mph on the Hwy. (Yes, that was me that passed you. Get over it because I'll do it again tomorrow.) Now, let's say I get 20 mpg out of a 2011 Silverado... no wait, let's just say I can squeeze 28 mpg out of it! You'd think I would JUMP at the chance, but no so fast.

In the Dallas/Fort Worth area, if I want an LTZ Chevy with the Nav and Entertainment packages, I'd be doing REAL good to buy one for $52,000. I paid $34,900 for my 2010 LE loaded with the Navigation, and Entertainment package. That's a difference of $17,100. So it would cost me an extra $17k to buy the better gas mileage truck.

Now let's say hypothetically I can actually get 28 mpg out of the Chevy. There's a difference of 14 mpg. 14! Basically it would mean that I would need to double my gas tank every time I fill up. (Stay with me here...) So, the math:

Titan = $72 ($3 per gallon in a 24 gallon tank.)
Imaginary Chevy = $36 ($3 per gallon in a 12 gallon tank. Remember that it only costs me half as much gas.)
Difference between the two is $36.
Take the $17,100 and divide by 36 and you get 475. That's 475 fill ups to get my $17k back.

So, I will get my money back after 475 fill ups. What's that mean? Well, currently I fill up twice a week. (Yup, I put close to 40k per year on my truck.) So twice a week times 52 weeks equals 104 fill ups per year. 104? Nope, still not to 475. OK so for me to get back the extra $17k I put in to buy the Chevy, it would take me a little over 4 and a half years. At 4.6 years, I would start making money on my purchase.

4 1/2 years... By then I will have 180,000 miles on the truck. By then I will be looking to get another truck. I'd never break even because I don't keep trucks that long.

Now, if you change to a Ford Escort, are you going to save money? You bet. You'll save on the car note and gas, so you'll save a chunk of change, but will you be happy? Will you be able to tow your boat? What will you do when you need the pickup bed? What's that? You don't need a pickup? Well, then why did you buy the dang thing to begin with? You can't possibly complain about the gas mileage of a pickup, if you don't need a pickup. How about reality. Let's go back to the 20 mph that Chevy is claiming the truck will get. Will I get 20? No way, but for the sake of argument, let's say I do get 20. In reality, I will not start making my money back until 9.1 years if I fill up 104 times per year. 9.1 years people!

Do you want a truck? If so, the Titan is the cheapest truck you can buy in the Dallas/Fort Worth area. Does it suck gas? You bet, but you can buy a WHOLE lot of gas for the money that you save. I'm the extreme driver. 40k per year doing 80 on the freeway, when I can. Most of the time its stop and go. There aren't that many driving that many miles per year. That means that those who drive less will take LONGER to get their money back. LONGER!!! Go ahead and find a comparable model Chevy/GMC/Dodge for the same price as the T. You can't. If you can, buy it, and I'll continue to pass your azz on I-35, only you won't be able to catch me in one of those other trucks ;-)

This is becoming comical. Yes, you can't just flash the ECU for larger/smaller tires but you can buy the hypertech speedo recalibrator and install that. You are calculating mpg but are you correcting for tire size? You talk about non-oem tires and that is all great but as with any mod, its not just the size but the weight that affects the mpg. Your 265 over the 245s have a higher friction between the tire and the road, this requires more power to overcome and etc....

Another thing you are overlooking is that it is winter time. They gas blend is slightly different and thus lower mpg. Then you add the E10 crap in there and it drops more. Then you need to look at what the published mpgs are and at which speed they are obtained. Most city is stop/go with 35mph but most hwy is something like 65mph. You are probably going 70+ and thus the lower mpg.

If at the end of the day you are still not satisified, then see if you can return the truck and get something else. It probably won't happen but you could always try it.

I have had 8 Nissans in my life and all of them have were not gas efficient...but man I love a good product with no other costs except regular maintenance...Yea I just put on these Nitto Trails 285/65/18 and dropped my stock 17" and I see the gas gauge dropping every day but what a truck...cant see me driving anything else.... go feel the power and enjoy a great pick up truck. Happy driving....

Excellent points! I have LT tires that are load range D. Even though they are the OEM size these mothers are heavy and I only have them on my Titan when I tow. The Winter gas in the Colorado front range sucks. It's an automatic 1 to 3 MPG drain. The MPG difference between 65 and 75 MPH is astonishing. A friend of mine drove his '07 4x4 Armada with me to California this summer. He complained like crazy about me driving so slow. But after he fueled up a couple of times and calculated his MPG he shut up. He had not realized his Armada could get over 20 MPG.

hey dubie-
i am well aware of all the 'different' factors: winter fuel, different tires, speed.
also keep in mind that it 'came' with E range 18's on it and that i HAD NO IDEA that the tire size was not 'factory let alone not changable in the computer'. i had just assumed that since it was an off road package that 18's came w/ it AND i also assumed that i could change the computer just like i had done on all my previous vehicles - not such the case.

i am also aware of the hypertech option; just found that one the other day... as for returning the truck - not quite at this time...
