Going to JD's Saturday to dyno my car again. The last time we dynoed my car was in september and I have installed a billet-flow T-boby and 12 inch air filter and a retune from JDM(Jim).The car runs so good this way just looking for more pwr. Once we see how much pwr it makes them I will put my new 2.75 sure-grip pulley on. This time I will get a new tune from Joe(JD's) to see how much better the auto-logic is then my super chip.... Looking for more then 500 hp with out those noisey headers.
