I need to get this A/F straightened out... looks like im taking it back to the great people at Next Level Performance for a tune! I was shooting for 330 so im happy with these results, we'll see what the tune will do. Im sure alot of you have heard good things about Mike Norris and his crew so im just another to add to the list of extremely satisfied customers.

Nice gains man. Yeah, your A/F is seriously messed up. Get that fixed and you'll meet your goals easily. Get an LS6 intake if you don't already, and that will give you great all around numbers.

Are these gains from stock full exhaust? After tune and LS6, this thing will rock even more. Wow hell of a gain back to back. Most guys don't see that much back to back, usually need to get 100 miles or so. TTT(Time To Tune).
