Dynojet reads normal, has been known by shops to manipulate figures, it calculates power based on the

Mustang dyno puts down a lower true whp reading, it's a load absorption dyno versus inertia, simulates actual road conditions much better than a inertia Dynojet
Dynapack connects to the hub of the car and read the highest of the 3 and doesn't show the actual to the tire rwhp. BUT personally for all peak tuning purposes I would use the dynapack because it gets rid of the wheel/tire factor involved and it's the closest thing to an actual engine dyno to get it precisely tuned.
Anyways dynos should only be used for tuning purposes and not really a HP factor but if all cars are dyno'd on same day, same dyno location then that is useful to gauge a good amount of cars. You really can't compare a stock STi in NJ, CO and CA and expect to have the same #'s on a forum when they are running on different dynos, dyno models, software, let alone temperature, elevation differences and multiple other factors.
Mustang dyno and 1/4mile slips are truth tellers.
