Can you run your log again? Just one full throttle pull from 2500 to redline in 3rd gear.

It's possible for boost to blip up for a very short period between shifts. What you need to look at is the boost across the rev range in one pull with at most one shift.

I will do that at lunch and post it but I'm not seeing 28 psi while shifting, it happens during the pull right before I shift then it goes to map 8.
See below, white is Boost, grey is RPM and purple is Map

Silly reference question: After putting in JB1 it does say to WOT a few times for relearn. Where did y'all find the space to send it for that? Everywhere I go is traffic.

I just floor it in neutral.

Well, it aint! ;)
So I logged some more 3rd gear pulls in Map 6, 1 & 0 with the boost safety set @ 30 psi so it wouldn't switch to the safety map.

In map 6 the requested boost was 25-26 psi and actual boost was 15-16 (limited by map 6)
In map 1 the requested boost was 23-24 psi and actual boost was 27-28 (4 psi added by map 1)
In map 0 the requested boost was 24-25 psi and actual boost was 24-25 (No boost added by map 0)

So based on this info my ECU is definitely tuned. Now I just need to find out by who and what stage.

Looks like Stage 1 or 1+. I'd start with APR, then Unitronic.
I just received confirmation from APR, I guess I need to work on a stacked Map 6 tune. This explains why the car seemed much faster than my previous MK6 GLI!

Your vehicle was tuned by us on 05/29/19 by New German Performance Nova to a stage 1 tune on 93 octane.

Or sell the JB4, enjoy your 1+, and spend the money on other stuff like tires, wheels, sway bar, etc.
