Hello- I have a 2019 Roush stage 3 with <20k miles (all factory with Roush supercharger). Emissions is showing up as N/A so took to Roush certified dealer and they still can’t figure out the issue.
They did the drive cycle and tapped into ECU and car shows up perfect.
Has anyone else...
So we recently installed the 767HP package and dyno tuned a 2015 GT with the Roush Supercharger kit and it made an impressive 682RWHP on 93 Octane.
We are very impressed with the numbers from this car with only 10LBs of boost. Check out the video below for more info
