New to the forum, not new to the Grand Prix. My 2002 GTP is the second Grand Prix I've owned (the other was a Silver 1998 GT). My dad had a 1963 Grand Prix Coupe he bought new in '63. It was sort of a powder blue. Wish we still owned it! Anyway, I've been upgrading my GTP each year with performance enhancements. This year she got headers and a canned tune, along with a 3.5" supercharger pulley and new plugs and 10.5mm wires. I have a bit of debugging/fine-tuning to do, but she's a whole different hot rod already!
