I have done every other bolt-on except for a pulley, now its time for your thoughts, if i get a 3.10 pulley what are the performance gains i should expect to notice? And i want to have the car tuned because it has a JLT ram air, and an x pipe, and i want to achieve the most bang for the buck out of the mods i have, i live near ohare, does anyone know of a good tuning shop that is somewhat close? i have thought about speed inc, what are your thoughts
