Hey I'm wondering how you figured out your corrected numbers.. My car was tuned on a mustang dyno and I'm wondering if it's making more power than I think it is...

Most mustang dyno read low ur tuner should be able to tell you if his is dialed in for correction.

Mustang dyno are 10%-15% lower readings than a dynojet.

Well I'm pretty confused so I figured id ask you to see if you could answer my question...
If my car made 316whp/320wtq on a mustang dyno with what I believe had a 1.2 cf are my numbers still 10-15% lower than a dyno jet? Or does the cf make up for the percent?
