Just fitted my "stage 2/195 upgrade" to my OFAC managed Orion.
Beiges, and P1 Superchip... Car runs lovely and bizarrely enough i've had to back 0.2bar of fuel pressure off at idle over the standard blues!?

Anyway, ive adjusted the boost to around 1Bar, which is runs happily most of the time... Every now and then it misfires when on boost, only once or twice and then settles - any ideas?
