Truck hit the rollers yesterday. 203rwhp at 3800rpm and 331ft lbs at 2700rpm. Not bad for a mildly modified 6.5L. I think I could have picked up maybe ten extra horse though. I was already running super clean by about 3000rpm. I think with a touch more fuel I could have done better. This was with the stock GM-3 set at 15psi.

JiFaire edit: Included the Dyno Sheet picture. OP also indicated it was a Mustang Dyno.
