You may want to edit that post and read the forum rules as you are not allowed to post street racing stories.

Programmer or not, my late gen 5.3 would walk allover your 4.3 and your pals 5.7 too. Booyah. You both could just follow the 275mm wide peel marks and ill see ya when you get there. Yeehaw.

Its funny cause my 05 Yukon (5.3) is heavier than the 07 Silvy (5.3), and my **** dyno tells me that the Yukon would hang a licking on the pickup, I can never get the wife to drag them with me and I cant drive both at the same time... It may be just me but the Yukon seems to pull harder. It got a new engine 30,000km ago though, and the pickup has 105,000 on it. Both are in tip top shape.
