Dude , I think I gave you my start settings awhile back. May be different from a single turbo but start low and push till it works without going over. Also I remember I told you about the gain setting needing tocome on slowly because if it spikes you need to back the percentage down. From everything you're saying , your plumbing has to be jacked up. My settings were:

SET=24%
Warning= 10.5
Limiter= 5%
Start= 7.5
Gain= Slow going after everything else is set, advancing till surging or spikes then back till it does'nt.

The only real numbers are Warning and Start, everything else is a percentage. Your start boost cannot be lower than wastegate and the limiter is the percentage of boost cut after you hit Warning. My set boost was at 24% to reach 9psi on a Single turbo. Not sure how that translates to twins. Also do you have external wastegates or an internal? You need to physically get under there and inspect where each line is going. What made it easy for me the first time was I had red for upper and blue for lower wastegate. That way there was no confusion on the back end. Also my boost reference is from the intake manifold and the signal boost comes from the drivers side charge pipe. Your system is common but it seems at this point you need to stop worrying about the people who could'nt do this right and drop a couple dollars to pay someone who knows to actually touch this and make it work. A good idea would be to hang around and watch them do it or show you what they did when it's done right. Don't feel all crazy about it either, because I just went through this with my fuel system and Charles had to pull me from the brink. Just like you I paid someone to do what I already knew and I assumed they did it right and in reality they screwed up something so simple I overlooked it because it was just that simple. You're in Oz and I've seen some monstrous builds going on there so people who know are definitely there for you. Good luck.
