OKay I bought my truck and already had the CAI and Tuner on it. The problem I am having with it is that the tune really doesn't seem to help HP or mpg. I am running 87 and did download the tune on her but really not worth it in my eyes. I have alot of buddies that dont have it that are getting better mpg and trying to find out if I need to get ready of this one and get a new model or what.

Dont get me wrong I like the power but it could never hurt to get a few more miles a tank. Stang Out

Year of truck and engine please............
