Boost disapeered !
One of our scoobys is playing up, only pulling 5psi all of a sudden (the misses broke it) I have removed intercooler and checked y pipe and checked as best as poss for any boost leaks, brand new dump valve , to just to eliminate the boost solanoid I un plumbed the line off the T piece in the actuator pipe and to my knowledge it should of over boosted like crazy with the solanoid disconnected with open T piece , but still only 5 psi . Checked the turbo and there's no play in the compressor wheel and free spinning.new maff sensor. Checked Ecu no codes logged but reset anyway. It's driving me crazy I just don't no where to look now any ideas would be greatly appreciated HELP !!!

Have a boost gauge in the car , just feels lack of boost otherwise drives fine , it's like someone switched off the turbo . Gonna swing by breakers today n pick up an actuator , I can't hear any boost leaks under load either

What's really bugging me is that when I removed the boost solanoid hose that's T'd into the actuator , it should of boosted stupidly even if it had a slight boost leak somewhere because in theory that T is a wide open mbc , but still only actuator pressure 5psi. So very confused lol

It will over boost if you leave all the boost control pipework off, connecting the actuator to the compressor housing will mean that it run at actuator spring pressure....
As said, put all the pipework back to standard and check that the restrictor pill is still fitted.
