This past weekend Engine Power built an turbo charged LSX engine. The single Precision turbo used was capable of 1400 hp. So who did they have to come in and do the tune during the dyno secession: Kenny D. The two guys were happy with the 1100 hp achieved but Kenny said with a few tweaks they could get more. A bigger intercooler and some work on the intake would help. He suggested just to cool the intercooler and they picked up over 100 hp. I think they were running 9:5 c/r and 15 lbs of boost.
