Default Please help...No more Sequential!

I have a 02 GS300 with Aristo 2JZGTE swap. Car has full fuel system and full 3" exhaust. I want to take the turbo setup out of sequential mode so it will make boost earlier on. Right now, i'm not seeing 17lbs until 3rd gear and high in the RPM's. I also have read that you get more throttle response. Now, I have read different forums that say unplug this vacuum hose and connect it here and plug this off and blah blah blah. I have also read that you can just use some wire and wire the gate open between the 2 turbos. Can someone help me and please tell me what the hell to do here? Now I have to go back and find a layout of the vacuum lines cause they are all jacked up now and the car wants to run hot when sitting and not moving. Please help!!!

if you arent seeing 17psi until 3rd gear youve got more problems then sequential mode. sounds like a massive boost leak or a smoked turbo.

Is there a way to pressurize the system to see if there is any boost leaks?

17lbs of boost on stock twins is pushing there limit!! Turbo or seals could be going or already gone. Wiring the flaps open with a wire is a quick way to keep em in full twin mode, eliminating sequential mode
