K14 'turned up' 12 psi before.... 10 after :/

[ADV_93]

Had EXACTLY the same with mine pal! Turned the fuelling up/boost compensator, went to turn up the turbo, released the lock nut and gave it 2 turns... Plugged mates boost gauge in and got 10 PSi... Then the following day, got underneath the car again and gave it a good winding in and then the bolt that winds in shaked and popped itself straight out into my hand... Where the monkey who had probably had the car before me threaded it or maybe it was down to the spring pressure on the threads itself, now i've got no screw in my wastegate so a breath of air and it opens, but still boosts at 13 psi... All i'd say mate is to make life easier, get a Manual Boost Controller.
