It's not that Dynojets suck. They're actually more accurately portraying engine hp imho. It's just that they give you a different number than whp. That, and people tend to be personally offended when you claim more power than their cars "illegitimately". E-penis inferiority complexes I call it. I mean, I personally don't like when somebody quotes dynojet numbers as whp, but that's a unit problem. The measurement itself is valid. It's kind of like elevation differences and temperature differences. It's just one more factor between the number (which is honestly rather vague and theoretical anyway) and actual performance.
Comparing to what it was stock is an excellent way to minimize the majority of outside factors. Saying you make "50% more than stock, when I started" when you measure before and after on any decent dyno is going to give a fairly clear indication of what the mods and tuning have accomplished.
If you're up front about the dyno being a dynojet, your numbers are certainly real enough. That's why we have a dyno type field when you enter your numbers in your profile. Subaru quotes at the flywheel, dynojets quote at the end of the driveshaft, and mustang dynos quote at the bottom of the tire. All three are equally valid, they're just different.
