Wondering how much boost can be run before the stock ignition will no longer work? I was running 20 psi and runing great, tried 110 racing gas and more boost and started to have a missing problem. Plugs are gapped about .029 vs stock spec of .034.

What kind of plug wires are you using. Might try closing the gap slightly for real high boost.

The stock ignition is pretty good when everything is right. These things are real sensitive about type/brand of plug wire.

Also are you sure you got enough fuel for that much boost. What year car and turbo do you have? Have you upgraded from the stock pump?

Plug wires are Motorcraft Racing wires (blue). Fuel system is upgraded, pump and pressure. 87 engine with ported head, intake, exhaust. T3 turbo with Ford Motorsport front mount intercooler. Plug gap reduced by .005
