I'm trying to find out if any one has a good guess of what my truck will run in 1/4 mile? I have a gmc 2003 2500HD with vararam's king cobra ram air, GR mass air flow, air raid intake tube, VR VELOCITY STACK, thorttle body spacer, nelson tuner,bed cover, and 50 sires flow master 3" in 3" out. 265 tries
I have not put on the tuner yet but i'm going to order it very SOON I WILL POST MY 1/4 AFTER I GIT THE TUNER
the nelson tune isnt like a hypertech hand held programmer. allen nelson will custom tune a pcm for you and ship it to you.
if its a 4 door...you'll run mid to hi 15's prolly :hshake:
it's a extcab but i still think that your about right i'm hoping for lower to mid 15's
did you ever run your's with out the 305's but with the turbo
nope...started off with 285/75/16 bfg at's and then went to 305 but i do want to run it with stock size or close to stock size tires to get a better run...this guy down here ran a 14.0 friday night with the same truck as mine accept he had the 60 turbo and stock tires.with upgrade 67 turbo inner cooler and stock tires..i should get into the 13's no problem...Quote:
