If I hadn't had my heart set on trying a supercharger setup this time around, I would have let Boosted Performance have Zuma for a test fit and install. Seen the results of BP's work around town for years, his own Z, and MANY happy customers with 350Z's and it is ALL top notch.
That says a lot to this company as I don't let a lot of people/places touch my Zuma for a lot of reasons, which is why I wind up doing most of the work myself.
Not to mention, I don't like paying shop rates
