hmm. I can easily hit 20 if I do that. Perhaps my own cheapo boost gauge is the problem. I've ordered a second hand one that promises to be better quality so I'll see what happens then
Revving the engine while stationary isn't the best way or in fact normal way of measuring boost. It has to be done on the road with a LOAD on the engine/turbo. A hill on a long stretch of motorway in top gear, foot down will likely show max boost. RPM doesn't necessarily correlate with boost.
My boost guage is plumbed in before the MAP sensor, I did this because I wanted to see what the ECU was actually getting. It's normal to get slightly higher pressure readings from the wastegate but this can be a false reading to what the engine is actually getting.
