That setup felt better but then I did the FMIC and started learning how to tune it. After 3 seperate tunes the thing was haulkin *** compared to the original setup. On the new setup I was actually spinning all 4 tires and the top end charge was insane.

I never made an offical track run on the first combo since the fire happened the same night I picked it up but I did get 1 GTech run. About 1/2 way through the run I lose oil pressure after a check valve failed and spewed a ton of oil outside the truck but I went 12.8@100mph 1.7 60'. I couldn't figure out why the truck nosed over but like an idiot I stayed in it because boost and fuel looked good. I think had it not nosed over I would have trapped about 105mph on the GTimer. We all know that they are usually a few MPH too high though.

I feel pretty confident that the last combo was between 520-550rwhp to be able to run the MPH it did with the trans slipping so bad. For you calculation guys it was 110mph on a 5250lb raceweight.

Well, the meth injection kit and 10 lb pulley will be going on this weekends. This should be insane for a novice like me!
