Chasing down boost issue

Chasing down boost issue
Simplified sequential on stock twins. Everything seems to be running really well, but I can't seem to boost over 8psi, and when it seems to drop down to around 6 when I hit secondary. Just tried blocking off hoses to wastegate to see what happens and immediately was up to ~12-13psi. I didn't stay in it to see what happens during transition to secondary but AFRs were still safe at about 11.9. Curious about any ideas on where to start tracking down what may be keeping me from controlling boost with my Adaptronic ECU.

What are you using for boost control? Stock wastegate/precontrol solenoids or aftermarket solenoids?
This sounds just like a stock car with the pills in the waste gate line missing. Also spring pressure on the waste gate is 7psi.

Bingo, there you go. You should get good aftermarket solenoids and control them with the Adaptronic. Or get a good aftermarket boost controller.

You can probably hook up the new MAC valve like the "version 2" set up -

I've been running my AVC-R for YEARS like this. Fantastic response and solid boost control. I don't see a reason that you absolutely have to run the precontrol separate with an aftermarket controller.
