I've been dicking about with mine (managed to sort out my cooling fan problem by bypassing the poxy fuses and sorted a snapped bolt in my alternator) but I've noticed a drop in boost pressure.

Would not having any circlips on the 'mbc' (AKA 'bleed valve') piping be enough to cause a drop??

I'm guessing a pound or two of psi is easy to drop from the smallest of leaks, but I'm looking for some expert advice and opinions :)
