I went out to APTuning on Friday and got the December special for OBD2 2.0's. The chip was $50 installed. I noticed the gain once I put some ultra 94 in the tank. If anyone needs a chip for their 2.0, and they live in PA, go there! They burn their own chips. Get his, my CEL went OFF after It was in for like a half-hour. They said it would be 5-7 hp gain, it is noticeable around 3500-5500 RPM, it just goes. I don't know if it removes the top speed governer, I don't need to go that fast.
