Just last week at the drags my car was running 18psi at around 95 degrees C.
Must be another issue there somewhere.

Thanks Edwin. You are right because Terry said "Is oil temp > 160 degrees? Needs to be for tuning to turn on!".
I always thought boost came on at 90 degrees celsius?

Ok thanks Peter, I'll check that first thing before this morning. I hope that is the cause as I have no idea what else it could be. When you say the hoses on the boost accumulators can be knocked off, at which end of the hose are you referring to? Peak boost is consistently around 7.5psi so I assumed JB4 was using the cold/hot oil protection safety feature. Boost gauge reads boost between -18 and -22 at idle which seems normal.
