Put on stock MAF and no CEL, so I called Pro-M and mine has an E engraved which is for elbow. Since I have a KKM, it is supposed to have a C for conical filter. Also the guy said that it is supposed to have the injector size engraved, but it doesn't. I was also supposed to get sheets that show the calibration, and I didn't get those either. Pro-M told me to send it back to Muscle Motors, so they can sent it back to them. I don't see why I couldn't just bypass Muscle Motors, since it doesn't seem to be their fault. Well that's where I am at.
