Roush Performance Packs

[Bobne]

2019 Mustang GT. The Roush performance pack 1 cost $1100 plus cost of a dealer installing the tune, and will give you a 24 hp increase. Is that low amount of hp increase really worth the money?

No if your wanting it to retain warranty I believe it’s only 36/36. Better off getting a custom tune. If e85 is a option and staying na best bang for the buck.
