GMC Performance Question

[spectratoad]

I have a 2000 Sierra pickup with the 5.7 engine, Lifted, flowmaster exhaust. I tow the boat once in awhile but use it mostly for work. Just looking for some ideas to increase the power/mileage a little bit. What are some starting points???
Chip, different exhaust, Flames :D etc.... Thanks for any info.

i'd suggest a k&n intake kit,hypertech powerprogrammer.it'll give you a little more bottom end and the free flow intake set up helps with the mileage.good for @25hp on a vortech 350.the spiral throttle body spacer really works to.i'm running one on a throttle body injected full size blazer and i could fell the difference.
