Ok only mod to the truck is an Efan swap as far as the base line. Other then the efan it was run completly stock. I have never had a dyno done before, and the guy that did it said they left it in second to do it. Seemed odd to me. I always thought u let it go through the gears....
Link below should take u to some pics of it. The tube is 3.5 inch. They tried a 4'' but they said the hemi liked the smaller tube.

Looks about right, last time I had mine on a dyno with a sc3815 CAI and Cutout it was pushing 271rwhp and 301rwtq. Sucks how badly the stock drive train eats power huh. As for the run they should have done a third gear pull. You run it til it hits third and then drop it into second I believe to hold it in third

Yep, same basic 8hp gain you get from any intake swap.
Looks like perhaps a lot of torque management going on with the up and down heartbeat looking lines in the upper rpm range.
a 100hp loss to the rear wheels is terrible. 345 down to 243!!! That is a 30% drivetrain loss to the rear wheels. Shame on Chrysler!!!
