Today I got my car dynoed at JBA racing in San Diego. I am a little skeptical about the numbers, they seem a little high.
Temp-60.5
RWHP-291.4 at 5965 RPM, Air/Fuel 11.6
TQ-299 at 4474 RPM

The only mods I have are flowmaster mufflers that are designed for the previous gen. mustangs and steeda udp. I told them that I thought 05-08 Mustangs are putting 255-265 RWP. He told me that is about right.

JBA uses a dyno dynamics instead of a dynojet. I have read that dyno dynamics read higher and I have also read that they read lower.

One thing I noticed is according to the A/F numbers, I am running too rich. At WOT I am at 10.0. Wonder if there is indeed something wrong my car or the numbers (RWHP,TQ, A/F) are off.

I would hold off on that(re-dyno).... if you are going to do something more to affect your HP then wait till you make some changes... who cares if it is a little off for whatever reason... you have a nice dyno from a good shop..

I had my car dynoed again from another shop. They used a dynojet and SAE numbers.

HP: 285.91
TQ: 287.36
Airfuel seems normal now. It read 12.5.

Maybe my car is a factory freak.

no that sounds about right on a dynojet. a stock s197 will read 275-280whp on a DJ.
