Hi, car's basically BPU, DP, dropin air filter, BCC, and just installed EVC4 running TTC. I noticed that my car idles rough now even after trying to adjust the idle. What could be causing rough idle? I don't think I have a boost leak cuz I can boost to 17psi, haven't tried higher, and vacuum is pretty steady at 20psi.

What type of spark plugs do you have? If you got the ever popular NGK 3330's, the rough idle is normal...Darshana S...
