Car been built and running great for year or so after 18PSI magic tune. Than last week I got a high RPM miss. Checked plugs an they looked great, replaced them anyway and gaped new ones to 25. I'm lost, runs great unless its WOT high in RPM range. You can see it.
There is a build thread under my SN.
