are you running any sort of boost controller...you can keep the lower rated wastegate springs in there and trick the system by using a controller. It would give you more boost but keep a fail safe if the controller were to crap out or malfunction and would revert back to the 13.5 psi (wastegate pressure) you have now.
just a suggestion

Yes we have an mbc on the car. Spiking at 23 and falling off to 13.5 at the top rpm range.
Why aren't you tuning the boost via the N75?
Although I never ran a MBC on any of my RS6s, some tuners prefer it because it's quicker and easier to raise the boost with it than it is to make PID adjustments and re-flash. You can make real time changes to the boost and then later on take care of it in the tune. Some of us also run tiny lightweight batteries which don't allow for flashing via OBD out on the street, so that adds more time when you have to pull the ECU, unscrew it, modify maps, calculate checksums, flash the ECM, reinstall in the car, etc. It gets to be a real pain in the ass when you're making dozens of file revisions. Perhaps adaptation channel 12 is the answer here but I haven't looked into it much.
If you want to get real wild, there's now a relatively affordable emulator that you can use to do real-time changes when tuning without flashing.
