I think 403 rwhp SAE on a Dynojet is the pump gas record. Most of these cars with bolt on mods range from about 375-395 rwhp SAE on a Dynojet. This one might be at the top end of that range but the OP would have to run on a DJ to know for sure. There are a bunch of Mustang results in the dyno database that would make the better comparisons. As noted, Mustangs tend to give lower numbers but at least the comparison would be more accurate and the OP would know where his results fit in the Mustang range for similarly modded cars.

I meant that as a general rule of thumb in my experience over hundreds of dyno pulls in several different cars. You extrapolate 412hp with the 15% correction and say no one has ever come close, then you state the record is only 9hp less lol. I don't know about you, but that sounds pretty close to me. Then, after using a dyno "record" as a measuring stick, you go on to explain that dyno measurements really are moot unless compared to similar cars on the same dyno. I hope you see the irony in that. Lastly, to say the test is discredited because the results did not fit your expectations isn't exactly fair either. What is interesting is that he did post what stock M3's dyno at 330 so in theory he made ~30hp which is a healthy amount of extra oomph at the wheels from intake, exhaust and tune.
