Im not disappoined with them but im not happy with them. Was hoping to make 600.
HP-578
TQ-946
I see 46 psi of boost on the street and only managed to build 38 on the dyno. Im not sure what a loss of 8psi equates to horsepower wise.

stock tuning yielded a whoping 276 hp lol

Godfrey, il
Don't b discouraged sean. Is the tq tuned down on purpose? I think witha couple tweaks u will b at your goal. Should b a low low 12 or even a high 11.

yeah i know that. it would be nice to have a 600+hp sheet tho. Everything in the logs looked great. rob was spot on with the tuning i must say. id like to get it to the track but im having some tranny issues, TC wont lock @ WOT and i think it may be slipping in the top end.

Only reason I say that is last time I ran on a dyno, I couldnt build enough boost either. It was in the 21-22psi range, instead of the normal 32-33 I see on the street. Truck only pulled 506 something. Had been hoping to hit 600. Operator said that usually its 10-1 hp-to-psi. I might have been fed total BS but at least I felt a bit better about things after that.

Im still sad that Dave Dunbar retired. Never got to dyno one last time with him.
