yes, if you switch there's a huge difference. I went from one to a Wheatley tune cause he's in Houston and I'm right by it so it made sense. but I noticed a huge difference. went from 13 mpg to 15.5 mpg even though I still drive the same and the power is beyond what a programmer can do for you..just sell it and use that money for the tune
