www.nelsonperformance.com Not only is my truck faster and more pleasurable to drive, but I gained 2MPG with my nelson tune.

Re: Wanna make my Z71 faster!! Need help please
Nice your getting all that air in with that intake, but trust me...it's not getting out as quick as it could and that means you're losing hp and efficiency. Slap some headers on that puppy. You won't be sorry.

Re: Wanna make my Z71 faster!! Need help please
lol how much do these newer trucks weigh? you want a kick ass truck, get a 73-87 chevy that weighs 4000 or less pounds and put a 383 or 400 smallblock in there lol... prolly pulls down at least 12 mpg in the city and can run 12's or 13's in the quarter with the right tires, on a mildly modified motor
