i need help. i just got my red top going it runs great but at idle it loads up and will begin to start fouling plugs after a min or so. i have a disco pot turbo. 555 inj at 43psi at idle with vac line hooked up. jwt ecu tuned for engine. z32 maf. im running bkr7eix plugs gapped at .030. any ideas on what i should check. timming at 15. its tough to drive in traffic without fouling plugs. as soon as i get on it and clean it out it runs great.

Do you have a wideband? I would guess maybe a boost leak, or intake leak. If you have an adjustable fpr, turn the pressure down a couple pounds and see if that helps clear it up at idle. I would drive it hard like that, but then you definately know what's going on.

A lot of guys run an safc with the jwt computer to clean it up a bit, hope this helps.

my guess would be its getting to much fuel lower the pressure and try it
