The drivetrain loss seems kind of high on these cars in comparison to the SRT automatics, most of those cars make about 370rwhp stock which is only about 15/16% loss compared to the 20/21% we saw on this car.
Heres a link to the dyno video, please ignore my verbal screwup on the baseline torque:
We said 9lbs on the vid, but after checking the text page on the dyno the car made 8lbs at the 6000rpm
Did you add or change out the fuel pump and install injectors?
