Customer Reviews:
Can't say enough good things about my experience

By Doug Thayer September 26th, 2012
It has been 14 months since I got the Phase II supercharger installed on my 2007 Mustang GT convertible at the Roush plant in Michigan.
Customer service exceeded expectations.
Performance of the car is unbelievable.
Absolutely zero problems since the install.
Can't say enough positive things about my experience.
I live in Canada and have installed numerous other Roush parts on my car.
Roush should pay me as a spokesman for their company
