I recently bought a 2004 Rumble Bee and the check engine light was on. It finally got fixed with replacing two 02 sensors and the cat. When I got it back it didn't have that hp like before. Found out that the computer was performance programmed and the dealer reset the computer and lost that setting. Well I want it back and was looking at the Superchip 3842.
What's your opinion on this selection and is it worth it?

 

Yes it is. Plus the tuner is capable of code reading/resetting.
