I realize that it also depends on how many WOT runs you do per tankful!
That's a tough one to answer, when most tunes go for output power, and it will all depend on how the driver is, fuel mix, etc.. That's what is great about turbo cars, if you keep you foot out of it you can get great gas mileage even tuned.
Since I only have tried COBB, I can't really give a great answer. But if great gas mileage is what you are looking for, I say your best bet is going pro tuned! With the goal of best mpgs
With a few WOT and daily commute, S1+ E50, Pro E-Tune by PTF. I just calculated 18+ mpgs. Not the best, but not bad for 400 whp.
