yeah. Looser stall with that monster turbo of yours would be a must. If I can remember correctly you have a gt42-82mm with a 1.30 a/r exhaust housing. If so that thing is a moster for that 5.3.

 

how is that coating holding up this time around?

 

You should have some wicked times if you get it to leave making boost. I am in the 11's and I am not making anywhere near the HP/TQ your sig says, but I am cutting 1.60 60'. your truck should be capable of lower 1.5's or 1.4's if you just get it to launch.
Also, I know a few people that have been running turbo's for a while, and they are using a 3 step instead of a 2step.

 

MJ, coating seems good this time

Joey, My truck is an ext. cab I don't think i could get that good of a sixty"
Tell me about the 3 step Thanks
