If your car JUST STARTS doing something out of no where for no reason. You didnt change anything.... then its most likely something has degraded or become loose, not aligned etc etc..

Search the reason why before throwing money at it because you will most likely buy something that will not fix your problem and you will just get pissed off because you wasted money and your **** is still broken

 

try spraying some wd40 on the acuator arm see if that helps.

ya stock maps are only good for 11.2lbs correct? and in my experience the more boost you run and the closer to the max of the stock map the less accurate they are. the money thing made me lol ha ha ha

 

When the weather here in central VA started getting around 55 my car started to hit boost cut and the only thing I can think of is the colder air? But it looks like you have solved your problem.

 

Same here in Ohio. When it got cold out I started to hit boost cut @24psi, which is creeping 2 psi from set point. I don't know the exact cause but I'm guessing because the air is colder/denser(therefor slightly compressed already) that is creating the extra few PSI? Sure seemed like it started just as it really got cold out.
