mysterious 5kcstq problem
> Car starts fine, idles fine, and runs out fine until you come into boost.
> On boost the car begins to buck and breakup. The behaviour is temperature
> sensitive, in that, if ambient is below 40 deg F, no breakup until say 1.2
> bar. If ambient is above say 65 deg, occurs around 1.0 bar, and as car
> heats up to full operating temperature the threshold drops to as low as 0.7

underneath it, especially at the wastegate end.
