Is there any way to have an MBC intalled in parallel with the N75 and boost not taper down???
I read lots of posts about the MBC setups in the archives and people said having the MBC only caused some drivability issues at high speeds as boost builds up too quickly due to lots of exhaust gas available, so I still want my N75 to control over boost yet would love to have higer boost near the redline since I have K04's and an adjustable FPR set at 5 bar in my car. I haven't got my car back yet but I'm already thinking about what I will do after I get the new clutch broken in. Will adjusting the N75 work with no problem? Just thinking out loud...if there's no solution, then I may just go AWE stage 3. Any input will be greatly appreciated!

No. If the MBC is installed in parallel, then whichever device has a lower setpoint...
(MBC or N75) will prevail and set the boost to that level. If you are running K03 software with an MBC in parallel, then the MBC will just cap the maximum boost. It won't prevent the boost taper from the K03 software.

Not entirely true really.
If you run MBC in parallel on K03 software with bigger than k03 turbos, the boost won't taper as much as it would with k03s. This may cause you to have a flat boost curve, capped at the MBC's setting all the way to redline, depending on your mods and MBC setting.

I don't see much taper at all ... I see an initial spike of around 20 psi, then 19.5 PSI or so
pretty much to redline, controlled by my MBC setting. I will run some more tests just to make sure, but if it was tappering alot I would have noticed it weeks ago.
