When coupled with the magnaflow exhaust S&B CAI I've also seen fuel mileage gains as well. You have to keep your foot out of the extra ponies you have to see it, but when I set my cruise on the highway at 70 I'm averaging around 22MPG. IMO it was worth it, I got it from Autoanything.com for $419 with our forumz discount of 16%.
Thanks for the information. Tuner is next mod and while i'm still shopping he options, its nice to hear that the thing noticeably works .
I wont be changing the CAI or Exhaust this year, but would still do performance tune . anything MPG is an improvement, im averaging like 12 or 13 and that's not a heavy foot.
