Loaded question... How can i get more pep out of my 4.2L without breaking the bank. i dont mind bending a little, but i dont want to go for broke...i am in the process of exhaust, and i already have the common k&n. any ideas???
exactly what trimble said! i have a magnaflow SI/DO setup, a K&N '77 series CAI, and an Xcal 3 tuned by Justin @ VMP Tuning. My truck has some pep!! but it will eventually be a killer! plan on keeping the truck for project work, and doing a possible twin turbo setup for the strip...but that is a LONG way off!
I agree with the Tuning, gearing, and intake. I got the XCAL2, AF1 intake and 4.56 gears. I'm quite impressed with my trucks get up and go. It tows the boat MUCH better now. I'm still on the fence about putting an after market exhaust on my 4.2L V6.

Do an underdrive pulley instead. People say they feel just as much of a difference compared to what they did from their 87 perf. tune.

Cool, I was thinking of doing pulley's as well as E-fans. Just wasn't sure about the quality of E-Fans... I read some bad and some good things about them.
