Default Stage 1/2/2+ poll: Stage/chip type/MBC?/TCD?/MBC set at x psi

Just looking for some setups for when I install mine as to where all the K03 boys run.
Mine will probably read something like: 1/Giac X/yes/no/16 psi. I might change the psi depending on how many are running 17 or 15 or whatever. It'll also be interesting to see how many people aren't running MBCs.

Default I would advise against MBC-only setups on K03s.

K03s are barely up to the task of running chipped boost levels (16-17 psi tapering to 12-14 psi) without popping. Asking them to hold 16+ psi to redline is a Bad Idea<sup>tm</sup>.

Default I thought the MBC just set the max, not what it would hold the boost at.

Am I mistaken in this thought? It just restricts the pressure; not sure how a regulator would request more boost.
Input please.

Default Never saw a need for a TCD, either, but that's why it's a poll.

Also, could you read my response to DAP and respond? I think I'm confused about how an MBC works...

Default If its installed in parallel with the N75, it will. But then no TCD is necessary since its just

limiting the boost spike.

The the MBC is put in place of the N75, then it controls boost entirely and holds the boost level at 16psi (or tries to anyway). If you have it that way and see boost taper, its likely because you are spinning the K03s as fast as they can go (not a good way to keep them alive).

MBC will limit the high boost spike that usually triggers the throttle cut
