buy it from crait engine depot much cheaper than at the dealership and install isnt much, let us know how the superchip goes if you go that route though if your not worried about your warranty, i suggest trifecta best tune for the money

I was trying to learn about my options on aftermarket vs GM also. Yesterday I spoke with the following sources: 2 race shops that do mostly Hondas and some other small cars, 3 high performance shops that do mostly fast cars like Vipers and Corvettes. Two of those people are very experienced racers that I have known for years. I have previously spoken with Hahn Racecraft and a buddy who is the parts manager at a Chevy dealership. Everyone except Hahn recommended the GM kit for street car use. That should tell you something, well it did for me. I'm going with the GM kit. Warrantied by GM, reasonable price, and still passes smog. Now that I've done some research it's a pretty easy decision.
