Not reaching max boost after stage 2

Hey guys, ive been having an issue since i went stage 2. I max at 18.5 but only reach 15. Sometimes it will go higher on my boost guage, but the needle will bounce. For example if it hits 17lbs it will hit 17, than bounce to 15 and keep losing 1 lb every time during that run. I first thought heat soak. But just went with neuspreds fmic yesterday and still having the issue. Now im thinking its a boost leak, or the actual stage 2 map (cobb). I already had awe dp to borla, and apr cai so i just ran stage 2 ots. Also im thinking its the forge atmospheric bov spacer after reading issues of them

Anyone have an idea?

So you were reaching max boost before switching maps?
Could log requested vs actual boost to see if there is an issue to start

Logging will give us the information needed to make an informed decision. If your car is requesting like 18 and you are getting 15, then there may be a leak. But if its requesting 15 then its a different story.
It is also pretty hot in florida. Heat soak could be an issue.
Since you are cobb, can't you take logs with the AP device? Or use VAGCOM

When did you install the spacer? Pre or post tune?

Pre tune. But i did some research and i guess im having boost surging. Tried to run logging with my vcds but it all just deleted. Not entirely sure how to save the logs.. only happens with high boost. Stock tune is fine. Gonna try renoving the spacer. Talked to cobb too to see if the ots map may be causing it also

The forge spacer is fine around town but you will lose boost between shifts. If you have the carbonio stage 2 pipe, check the pcv connection in the back.
