I wonder if he printed out an SAE corrected sheet. I've heard you can really play with the numbers on a Mustang Dyno to make them read in your favor. I'll put it this way I dyno'd on a Dyno Jet and got 313 rwhp and 325 rwtq with long tubes, o/r x pipe, steeda under drive pulleys, jlt and the 93 race tune from Doug at Bamachips, I don't think it is even possible to make the power that your dyno sheet says with just an intake and a tune. The catbacks aren't really going to account for anything. If I'm wrong, I'm wrong and maybe I need to have that guy tune my car, but I know Doug at Bamachips hasn't even found that kind of power in his own car yet and he's already swapped out the cams.
Did you also notice your A/F numbers ?? even if your max Hp and Torque results are accurate ?? your tuner obviously leaned out your A/F ratio in order to get those results..A safe A/F ratio should be no higher than 12.8 to 1-13.1 to 1 your A/F numbers are 13.4 to 1-14.5 to 1 which is rather lean for a N/A application..
even with a rather high a/f ratio, that still is not going to account for the kind of power with those mods.
Absolutely no way to get that RWHP with those mods...IMPOSSIBLE...may get that HP at the flywheel. RD
