What brand are you guys tuning on Ess m3? Ess told me to use stock but I seem to have power issues, like the rpm struggles on 6 to 7 K rpm. I have stock spark plugs( newly installed when I got the supercharger) could the issue be my spark plugs or my old coil packs.
I m sorry man, because some guy from a tuning shop is telling me that I can't use stock, it confuses me.
