I know pretty much everyone who is dissapointed w/ there #'s ask this question. But I have a 2006 Ford mustang GT 5 speed. Steeda UDPs, Mac offroad prochamber, JLT II CAI and SCT tune. Does 288/305 in 4th seem right? I was sure atleast 300 would be out of that setup

 

those numbers would sound normal to me,
if the udp's & exhaust were not in the equation

 

So you think I am low?

 

Yeah 300 doesnt seem to far out of the question.....what is your baseline dyno though?? The gains are what matters not you "end" hp. If you started at 255 they are bad...if you started at 270 i would want money back on something....

 

This is my first time on the dyno so I don't knwo what my gains were. But I think this dyno just reads low because there was a 2002 auto w/ flowmasters, K&N intake and predator tuner only put out 223.

 

Could be because i think they dyno stock around 220-230

 

Thats what I thought. Oh well. I still think itsa 300 hp car.

 

Brandon, I thought my dyno numbers were a little low when I did mine as well. After reading up some, the computers can be pretty finicky, especially when it comes to higher IATs. For as hot out as it was today, you are probably pretty much right on.

For what its worth, I put down 291/303 a few weeks ago on an equally hot day.

 

I put down 290/305 with flowmasters, intake/tune through a 5 speed, haven't dynoed it since my pypes h-pipeDyno jet #'s.

 

Those are good numbers 05 ricky! I had bassani race C&L street, BBR stage 1 cams, custom tune and I only put down 311/290
