Mine didn't suffer too badly. I can still get 350-400ish to a tank, and most of that is stop and go rush hour trafiic. This is just on a street tune tough. We'll see after the dyno tune if it gets any worse, though I doubt it will get much worse. And if it does, I most likely wont mind because the car will make a bit more power (with any luck).
Just keep in mind... the aftermarket ecu programs are there to maximize the effciencey of your motor, and to maximize your hp gains on top of making your car run a lot more smooth should you be running things like agressive cams.
