If thats on a dynojet, I'd say there's a good bit left in there, probably another 40 horsepower I would guess. On a mustang dyno those numbers are a little low, but nothing crazy.

Are you auto or 6-speed?

Is that with the stock 10 bolt rear. It does seem kinda low, but elevation can suck up power big time. If it was dyno'd where you location says (Albuquerque), that's over a mile above sea level.

Why do you say it sucks? Are you thinking the motor is hurt?

no I just wanted to get the maximum power with my last tune. I had 400 rwhp when I bought the car wit stock heads nd ls6 intake. Then I added the 2.5 cnc ported TSP heads, FAST 92, ram-air, nd a cutout. Thought I'd get more than just an extra 8 rwhp.

You should be closer to 500 I would think. 2.5 5.3 heads and ms3 make around 480 and your cam isn't much smaller man. You sure that's corrected?

Unless it's on two different dynos, there's something pretty seriously weird. It should be making at least 450 to the wheels. What kind of torque did you make?
