    4tec turbo guys spark plug gap question

    anything past 18psi is stumbling, I am suspecting the factory gap is too much. What are you guys running? Of course I have done new plugs and coils, doesnt seem to matter. running 11.5 currently on 18psi and up so not rich enough to stumble in my opinion.

    I ran around 0.018" for my gap with high boost. No issues

    Thanks, being that it is your old setup I will take your advise. I was planning on trying .020 but I will go with what you were doing since that was working.
