New to the site. Just wanted to introduce myself and my truck. I have a 2001 gmc sierra. 408, s480 turbo, fabricated 9" and blah blah blah. I took it to our 1/8 mile here in Houston and ran a best of 8.3 at 88mph. My gear ratio is really killing me right now. I have 3.30 gears and 33" tall slicks. I ran the entire 1/8 mile in 1st gear. Its been tuned by Nelson but is in need a retune bad. Surges really bad and goes into 2nd gear at idle. Anyway heres some pics, hope to have some paint on it soon to.
