Totally dpends on what you got and what you want. For 009's i would probably go with Jim Testa. Straight up race chip probably Red Armstrong. Good cheap, reliable chip, Thrasher. Many, many others as well. Joe Lubrant makes a real good chip, but not in the game anymore as far as I know. Then again you could just get a ME and be done with it
Jay Carter, Ramchargers to add to the list. Don't forget that you need to upgrade your fuel system, when you want to go faster
(New fuel pump, hot wire kit, adjustable fuel pressure regulator, fuel pressure gauge. And then you will need a scan tool to tune and monitor with. The fun is just beginning... You will then get bit with Gofastitus
