EFI & Ignition Problem
I'm having problem with ignition miss at high RPM/boost and am wondering if anyone has ideas about where to begin?
The problem: when I'm on "extended" boost (i.e. longer than 1-2 sec) on track at 5000 RPM or higher, the car will literally buck & I can hear it misses. If I lift (& lose all the boost) then it will stop. And the bucking will get worst if I turn my boost up from 0.7 bar to 1.0 bar.
Could this be dwell? Spark plug gap? Or ???
