I have a 2003 ZX3 ATX..I have a MBRP Exhaust, Pipercross Short Ram Intake, and a DiabloSport Chip. I had one question...when I purchased my chip from McNews Automotive, they said that they had programed it and everything, but my rev limiter wasn't raised, my governer was not removed, and I noticed absolutely nothing different with the way my car drove. Now, I went back to McNews and they said that they had never heard that it would raise the rev limiter or eliminate the governer...but isn't that the point of the chip? I've had it for about 2 years now and I can't get a straight answer. Does anyone know for sure. I paid almost $300 for this chip and to me it has been useless. I honestly don't think McNews ever programed it. I'm just asking for help. This chip has never worked correctly since I've had it for 2 years. I don't want my money to be wasted.
