Depends on the dyno, how much boost you're making and a few other variables. Assuming the listed mods in your sig are up to date, 22psi and 15-16* max timing on 93 octane;

Mustang dyno: 265-275whp/315-325wtrq
Dynojet: 300-310whp/340-355wtrq
Dynocom: 315-325whp/350-360wtrq

Just a few educated guesses. Let us now how you made out..

Without a proper intake and around 22psi you'll be lucky if you're getting 300. Maybe 290ish. 345 350ish for torque.

I have same opinion...K&N says 12 HP for SRI...that would be MAX. I know they *tested* it for our car but those #s are always on the high side.

Bottom line..you got it dynoed by an AMATEUR....school sponsored program. The *tech* was prolly a student. Sorry about what happened...good idea to tell administration of the *experience*. ... ya get what you pay for . See a PRO next time around.
Good luck with the #s too.
