horsepower est.?

Can someone est. my hp? or show me how?
I had my car to the Dyno on 8-26-06, and it said I only put down 175hp and 211 torque. This was on a mustang dyno.
I think its 20-30% too low, If my stock is 190 at the flywheel. (I know its less now, the bottom end has 100,000 miles on it) Everything I have done is in my sig.
Thanks for any help. I'll help out in any way I can if you need more info.
I'm going to take my car back in the Spring to have them fine tune it for me.
LOL....or take it to another shop.

did you say that you are going to have the prom tunned in the spring?

if it is not tuned than you are more than likely loosing hp by doing all that stuff. especially the 24 lb injectors

its already been tunned with everything Ive done. They had it for about a week. They had to buy new software for the TPI and they were doing test runs getting the new software working properly. I know they said the AFR was a little on the high side, but nothing that I would really notice.
The car runs simple awsome. I can powerbrake the tires, take off, and keep smoking the tires into 2nd gear. Thats why I cant see my car only putting down 175hp and the rear wheels.
