Since you have access to a pressure tester try this... hook up compressed air to a gauge, to the wastegate actuator line with your car off... listen for sounds and watch the pressure.
If it drops you either have a leak in the line, or the diaphram on your actuator might be chalked.
If the arm moves w/ no problems and no leaking, then it has to be either the mbc or the wastegate is cracked.
If the line takes more pressure than normal and then pops open, then there is something causing the wastegate to stick.
Lastly, what gear are setting your mbc? I did mine in 4th gear...
Hopefully someone else can chip in because I don't know a lot about these things, just trying to put my head to use... it would seem to me that if its holding stock boost then its alright. I only usually hear from people having problems with the stock wastegate when they set it higher like 17 and 18 psi or so...
