Hey y'all question about the zzp pcm upgrade to run the basic mods like pulley CAI and exhaust... wondering if anyone has done this out here in CA recently and had to pass smog? I know they just passed some new laws last year and zzp said I need to do some research to find out if I can still pass smog even if I keep my stock pcm and just switch them back when the time comes? Wondering if my ECU will still show the smog shop that I've done this change and therefore fail me? Any information very appreciated thanks guys
