Only had it installed for a week, have noticed gas mileage improvement. Have not been on any long trips yet to really how big of an improvement

Installed about a week and half ago. So far so good noticed a power increase pretty much in all rpm ranges. Mileage seemed to be better if I keep my foot out of it. Running the more aggressive map and there is no knocking.
