For those who understand the twins...
Mods are: downpipe, high flow cat and profecB 2 (pretty mild stuff). I got the profec to get rid of an instant drop to 8psi at 5600rpm and it completely cured it. I'm running the stock pre-control pill.
My issue is that after trying every possible setting on the profec, the best pattern I can get in 3rd gear is ~9.4 - 7 - 10.2 (and hold ~9.5psi to redline). By increasing the boost on the controller, I can get 10 - 7.5 - 11+ but at that point I'm hitting fuel cut in 4th gear around 6k rpm. The only way I can avoid fuel cut at higher rpm is to lower my settings, which in turn drops the 1st turbo below 10psi. BTW, I'm getting these readings from the profec and a boost gauge.
I've checked all solenoids, actuators and hoses and everything is working properly... the only thing I havent done is pressurised the system to see if maybe I have a boost leak (but I wouldnt think so since I can easily get to 11psi when both turbos are on).
I've messed around with a manual valve in the pre-control line but the best I could get was 10-6-10 pattern.
Does my current pattern sound normal or do you guys think there's a problem somewhere?

I'm not trying to boost over 10psi, I'm trying to get 10psi from the 1st turbo without having to go over 10psi when both turbos are on.

So, people who are using version 2 (Teeing the wastegate and precontrol together), what boost pattern are you getting?
I dont understand how version 2 could work properly... precontrol and wastegate actuators dont serve the same function and shouldnt be getting the same signal. But I'm sure I'll end up giving it a try anyways lol. If anything, I wonder if 2 profecs, one controlling the wastegate and another controlling the precontrol would work.
