Not bad for stock turbo and a heavy ass truck
I didn't think so, the numbers on the left where from my buddies 2wd extended cab duramax with efi. He is also lowered with nitto 420s so he had traction
You were spinning in 4wd?
Probably. The 4th and 5th tunes I had on my lbz made me spin 1st-3rd gear even in 4wd and then it would ketch traction. Lol
Never went down the track in 4wd, but did test it on an open stretch of road and still spun from 1-2. Not a big fan of 4wd launches rather not break tie rods
