I have a 88 fox with a 4.6 4v motor and a turbo with a lentech 4r70w. using megasquirt2 v3 for a ecu. Car runs great on low boost(14psi) when i make the switch to high boost(24psi) no matter what heat range plug or gap, it is blowing out spark. i have tried gapping plugs at .030 .025 .020 .015 and now .006 still having issues. I have tried oem coils, autozone coils, and i am now using msd coils with msd wires.
My question out to you guys is, who has used the boost a spark and had luck with it? Do you think it might help with my problem?
