Hey everyone, I have a 2v 03 gt supercharged and blower cams. Can too big of a cam affect the idle. I have had 3 tuners and no one can get it to ilde smoothly. It will get somewhat better if the car is in N . It's a automatic
Yes a cam can cause a rough idle but tuners should be able to smooth it out. Contact COMP to confirm if they have a recommended idle RPM and if it is a street cam. My bet its not the cam.
