hard to say, not sure im' a fan of either solution
if i had to choose, your way is probably the best:
MBC in parallel, bump BC, and no TCD.
you *might* get neg deviation up top but it wont hurt anything.

Negative deviation with N75 in the loop = limp mode.
I'd try logging with BC maxxed and seeing what you had to work with before brainstorming too much.
MBC in parallel sucks on AWE boost curve (without TCD) becuase you get the sucky mid-range while clipping the top end. The whole point of running an MBC on AWE stage 3 is to get some mid-range back in addition to clipping the top end boost.
MBC in parallel and TCD is probably the best bet.

I'm gonna go ahead and agree with Nye on this one...
Parallel MBC with no TCD and request at 255 works well on that setup. He just needs to pull timing out to keep those CF's <6, and he's golden.
God I hate that file.

Tried this and got weird results...
Installed MBC in parallel (plugged bleed hole), hooked N75 back up, set GIAC BC to 255. The boost peaks to almost 20 psi, drops to 18 before 3500 rpm, then starts creeping back up again. I did not expect this behavior. Any ideas?

By the way, do you have any screeching sounds coming off high boost? Sometimes I hear a weird screech sound. Sounds almost like a screechy wastegate opening up. Def not a turbo lady noise. The laser red S4 in boulder did this a little too. I think Dain's Nogaro S4 did it too.
