Ok, 20 degrees of timing with 12 PSI of boost? Again I'm certainly no expert on boosted engines but seems high to me, certainly at 12.5 AFR, have you ever looked at the plugs on this thing? While I'm all in on the weak valve spring theory, maybe as Adger had eluded to you have a few issues instead on merely one. BTW is this a new engine, I mean fresh engine and have you spoken to the engine builder? Who engine controller are you using? Joe
