It started knocking about a year after I bought it..My tuner figured out that it wasn't tuned for the mods it had done to it. My car is the silver metallic cobra with chrome saleens and a saleen wing. It hasen't been there a while it was at the dealership mostly.
Send me a PM when you're ready to go but with my shitto drag radials I probably won't hook.
What did the previous owner do to it which he didn't account for with a tune?
