if you are about to shift at 6000 rpm and youre at 14psi of boost and your TB shuts, your charge pipes (for a brief second until the bov opens) are pressurized while while your plenum is in vacuum - where do you want pressure and where do you want vacuum at that moment when you shift in your waste gates?
I would think you'd want pressure pushing open simultaneously while vacuum pulling open the waste gates to allow exhaust to bypass your turbine? This is how I understand it...
Top is top, bottom is bottom LOL
Top is what connects to boost controller, bottom is what connects to manifold pressure as far as I know. I went by the instructions with the turbo kit and boost controller.
I do see your point though, you might be right. I'm gonna try to redo mine and see if it makes any difference. The sound the car makes when I let off throttle does sound a bit like compressor surge, so this might be a fix. Took it to few shops and they said its normal.
