its the stage 1 cam and the street heat intake. the guy put a chip in it that he programmed with the sniper software. he pulled it out a few times to reprogram it. im new to tis dyno and tuning thing. my main concern was to keep the plugs from getting all sooted up
Did you get an A/F readout when you got dyno'd? My old 5.0 with the same TFS Stage 1 cam, AFR 165 heads, and stock Cobra intake (which should peak LOWER than your TFS intake) peaked at 5,450.
I'd like to see an actual graph of your #'s to see if there's any flat spots at the top of the rpm band.
