AVC-R problems
I have done quite a few setups on the AVC-R (mostly singles), so I would offer my humble opinion. If you don't want to run TTC, there may be other things to try than dropping the boost pressure or changing the start duty. Lowering the pressure will probably still spike, but be in safe levels, so it isn't the best compromise. Changing the start duty would work if you happen to shift at the right point, so again a way to compromise.
I would go in and actually edit the individual rpm points for boost solenoid duty cycle instead of picking just one and letting the AVC-R try to figure it out. That way you could bump it up during your prespool time and then back it off when it spools again. I don't know how accurate you can be with this but I bet if you place three NE points in succession with each the minimum 500 rpms apart, all situated around your prespool area you could probably get it pretty close. Then perhaps you could get a better pressure. You could also try editing the target pressure map NE points as well. Turn it down a bit during the #2 spool up and then jack it up when it is behaving safely. Naturally, you want to get rid of the fuzzy logic crap to do this or it will totally mess with your settings if it ever decides it has a good point to start with.
I think with the big FMIC, the computer will try to react too fast to the fact that it thinks the pressure isn't arriving at the duty cycle it is working with even though the pressure is just taking a bit of time to make it through the whole intercooler piping. You could try increasing the reaction time to see if that helps, but that is more just to control how fast it makes changes to the duty cycle for all points. I would try varying the duty cycle with rpm's and turn the learn mode off.
