I am getting overboosting cut out problems with my recently PPP'd MY01. Dealer cant seem to find a problem, they have fitted an new PPP ECU but still not right. Vehicle is in dry dock at mo, so can anyone give any clues to cause / cure please. (using only Optimax)

Overfilled with oil and oozing into restrictor and boost control tubing or sticking solenoid? - Solution to all - clean out with brake cleaner spray - allow to evaporate before restarting car.
If it always overboosted since the PPP was fitted you can usually sort it (short of an electronic problem) by changing the size of the restrictor.

Agree with John, and a quick one for John whilst hes here 
what is the size of the restrictor on my MY00? is it 1.2mm and if so do i need to drill to 1.3mm cos of my very light overboost (which is slightly annoying upto 120(kmh of course )
