Post the graph and log if you have it. What gear and how high did they take it rpm wise? Stock car with roush kit?

Dynos a tool. Best used for comparing changes made back to back. A lot of variables in its accuracy. Did they advise what they were seeing stock mustangs put down?

ive had a 2014 with a roush blower, 2019 with whipple, currently have a 22 mach1 being built. that sounds low to me. If you consider 15% drivetrain loss, thats approx 600 at the motor. I do agree with grimreaper, there are some variable and seeing the graph would help.

I had the 727 kit on mine and was 595 at the wheels (high altitude). Yours seems real low.

Do you have the Low Temp Radiator? That and the tune is what differs from Phase 1. Stages are for Roush-built cars. I'd still say your numbers are low, even if you have Phase 1.
