Hey guys - looking for some of your expert info on this tuner. It appeals to me based on the option to go between performance tuning and econ tuning according to what I read in the specs. I see plenty of posts and info on the performance gains, wondering if anyone has used the econo tuning options and have any specific information on it. I do a lot of in town driving, I wouldn't mind running with that option when I'm staring at lots of stop lights. Just wanting to make sure it's worth the investment before I throw down the cash. Any info would be greatly appreciated. Thanks all.
