Keep in mind that Im in FL where it was over 90 degrees today and I also have a little bit of an exhaust leak.

Does the AFR look ok?

 

One, not being a dick, but don't waste $ on a Mustang dyno, go to a dynojet. Your numbers are comparable to a stock 5spd on a dynojet. Your a/f is rich up high, if you lean it a little, so it's sage you will also seem some more power.

 

looks rich, should be around 13.0 - 13.5 or so... shouldn't dyno a car with an exhaust leak it does affect the a/f #'s

Numbers look good for a Mustang Dyno, those were corrected #'s Im sure so weather wouldn't be a factor.

 

It's just a small leak where the exhaust manifold-x-pipe meet do you think that could throw off the AFR to what the dyno read? Also the closest dynojet is about an hour and a half away and twice as expensive thats why i used the dynamometer.

 

The mustang dyno is much better for tuning, but if you want impressive numbers you should get a dyno jet done. lol. All the dyno jet is for is to "have more hp". Not bad numbers though.
