im new here but i took my truck to the rollers last month r so after i got back from houston getting my live tune from Wheatley!
3 gear pull,converter unlocked
329hp/399tq
horsepower peaked @ around 5300rpm so i may try some better heads in the coming months

well that's weird.....you would figure a cam of that size would be peaking past 6000 rpms. Torque peak is down pretty low too. I have a very similar cam in a 6 liter and it peaks right around 63-6400 rpms based on airflow.

Dyno graph doesn't cross at 5252?

Wheatley 04-29-2010 11:06 PM

Man it does peak really low!!
I would like to see the run started at a lower RPM with converter locked.
Scooter,sent you a pm

I just noticed that as well!!:bang:
Also,they hooked the wideband up didnt they? Just curious

Ya I wouldn't trust that dyno graph at all.

GMCtrk 04-29-2010 11:11 PM

good call Scott. Looks like the dyno is off. I'd be getting my money back.

Wheatley 04-29-2010 11:13 PM

mhotrodscooter 04-29-2010 11:20 PM
