I have been driving my truck for 2 days now and all I can say is that I must have got back a different truck.The Thorleys make the truck sound awesome. From a dead stop the stall really wakes up the truck.This TT3200 really acts different than my Yank 2800 stall in the 99 GMC.I am now really thinking about putting my bottle on the Z71,I am only worried that it won't hold up with 99,000 miles on it.I might spray a 100 shot,but I don't think the 150 will do it any good.What do you guys think?

 

you should add a shift kit. im thinking about a bottle after i put the cammed 6.0 in. then i will be really putting the trans to test i will have 100,000 on it..

 

Sounds like some good upgrades.
