It ran great on the little 3lbs of boost i ran, while we worked out the tune. Thanks to nonnie and Justin at BBP, they got it mostly squared away and we proceeded to get ready to turn up the boost. Well i went to 7psi and that ended badly with a busted 4l60e:



After this i opted for a stock 4l80 with a hd2 shift kit and a huges deep pan:



The truck today has run a best of 12.7 with these mods on a 7lb waste gate spring, there is more left in this as we have run into several snags on tuning the truck and are currently swapping some parts out to allow us to run a cos3 operating system so i can tune correctly for boost!
here is my track set up and how the truck currently sits:







Thanks for looking and leave any comments you may have!
