I have the Hypertech. It works well as far as I'm concerned. I get about 1 extra MPG using it, but the power is increased with WOT removed. There is no timing advance with Hypertech, but when I had BDGT I found that the timing advance only worsened my MPG. These are my results, and not that of others.

 

I had The Bully Dog GT Loved it for the performance gains. I don't really care about mpgs, If I did I wouldn't have bought a Titan. I would buy the Bully dog gt again in a heart beat. Or if your into performance look into Uprev. Little more money but the top of the line as far as our titans go. Oh ya and as far as used, the going rate is 250. If you get one you can pm me with any questions I can walk you through it if you need.

 

I already have the Hypertech Max, I got it for free off a guy, but his truck is still programmed into it. Customer support said to reprogram my truck costs $200. There's a Bullydog PowerPup locally on Craigslist for $200 that's been listed for awhile, I may be able to get it cheaper. Only thing is he says it's for a 2004-2009 Titan, not sure if it could be upgraded to my 2011?
From what I have seen and heard, I think I'd go for the BD if I can update it....

 

Are you looking for performance or mpgs?

 

Performance. I don't think one or two MPG's make much of a difference, not the way I drive most of the time. :devil:

 

I cant really say if there is a difference between the pp bully dog or the bdgt But I believe the pp bd Is more for fuel efficiency. check out Titantalk and here for a used one. Autoanything is a great place to do some research on the difference between the 2. I switched over to uprev, If I had to do it over gain I would have gone uprev before I bought anything else. I custom mounted mine like this. I only use it as a gauge now. The tune is pretty bad azz.

 

over on titan talk there's a guy selling uprev for 175 thats a crazy low price. jump on it but make sure its not married to the truck. like your other tuner. Dont make snap decisions but if its legit jump on it now.

 

ACK! Sold pretty quick, but thanks for the heads up!

 

As long as you do not have headers or cams, I would go with Hypertech. IMO the absolute best can tune you can for a Titan.
