jobee, there are others here that could do a better job of explaining your dyno graph, but I will give it a shot. First thing is the 330 hp you are refering to is the hp measured at the crank. The red number on the graph is you stock hp rating of 293.9 at the rear wheels. There is a loss of hp thru the driveline of 15% to 18% or so. Your best pull was 321.7 rwhp for a net gain of 27.8 rwhp. If you go back to crank hp you would be somewhere around 370 to 375 hp. Looks like you picked up about 27 t0 28 ft lbs tq.. These are not bad numbers depending on your mods. Dyno's vary greatly and the thing you need to focus on is the net gains and the shape of the power curve.

OK one of you tuners help us out here and please correct anything I said wrong.
