The lack of supercharger function was just a clip needing to be cleaned and a dab of dielectric grease. The mods are many including 4 new tires along with 4 TOYO PROXES R888's for spirited driving days This car has only 84k miles. Uninstalled parts are a Magnaflow TRU internal X-pipe muffler that would go where the rear cats are, then a Magnaflow "Y" to bring the dual outlets of the TRU X together with plans to remove the resonator and install the Borla Pro XS I have here, 3" offset inlet with a 3" center outlet. My mod list cost several thousand dollars and I am sure added 50-70HP as it is quick. mark, call me at 315-253-6088 My mod list also includes 550cc injectors and a PLXDevices wideband 02 sensor and gauge. I run an AFR in the mid to lower 11:1 range so anywhere between 11:1 and 11.5:1. This is a strong running car that cruises at a 14.7:1 AFR. It's likely Im have omitted some mods as having the car run correctly, safe and strong are my concerns, not trying to impress anyone with a mod list. Not many cars can run low 12's to high 11's and also tickle the spedo at 160MPH!
