I'm going to give a range...I'm not very good at this...umm...anywhere between 250rwhp and 1100rwhp. I think I got it. Run it and tell us the outcome.

Alrighty guys. Well I ran it and the numbers are very low. However obviously the butt dyno says different. I am wondering why the numbers are so low and it's not just because it's a Mustang Dyno. That is why I asked. I am wondering what my setup should make.

504rwhp @ 27PSI

504 is waaay low, especially with that much boost and a large exhaust housing. I made 530 on 93 octane with a PT72 dropping boost down to 16lbs at peak rpm(boost fell from 19psi at 4500 ((where my max torque was)) to 16psi by redline), you may want to do a compression check, at 27 psi you should be well into the 600's

I will do the compression check and also try her on a Dynojet just to see if something is up with that dyno. Everyone is getting bummed on that dyno with the numbers but when they take their cars out, the cars act like they have another 150rwhp or so in them. :dunno:

Looks like it needs a tune but that seems low to me. You should be around 540-550 on a Mustang Dyno with those boost levels.

looks real lean under full boost too 12.4? I would say you should hit at least 500rwhp on pump gas at about 18psi. Something is definately wrong.

I am working on richening it up at WOT and leaning it out more before WOT.

I did a compression test. We are going to retune the car and try again with weights in the trunk. Before the tires were spinning so I might have lost power due to that.

Supra compressions

1 150 psi
2 150 psi
3 130 psi
4 140 psi
5 130 psi
6 130 psi

Those compression numbers seem on the low side, If I remember compression should be in the 150's - 160. Those 130's could be trouble on it's way. I could be wrong with my numbers but im pretty sure 160 is what you want to be shooting for.
