Well, got to txt back and forth with the builder of this thing. He furnished dyno numbers and a video of the truck on it. He dyno'd at over 600hp on a stock transmission, said the engine was in good shape and never had any issues, has a batmo and some hot tuning from ppei. The transmission was beat to shit tho, said it was in need of a build in a bad way. Truck has hsp delete,cold side ic pipe, bigger downpipe and upgraded manifolds.
I sent a long email to the general manager of the dealer explaining everything so im hoping these guys will work with me on this. If not, oh well...move on down the line i guess.
