Stalling when reaching boost or 0 vacuum
I have recently swapped my 91 USDM NA to a S5 Jspec TII. It has a 3" downpipe and I'm still scrounging to get an exhaust. As it sits it'll drive and move around. I hooked a boost gauge up to monitor the pressure. When given more than half throttle it'll reach zero vacuum and the car will stall. Is this caused from lack of backpressure from an exhaust, rear rotor fuel cut, or what? Any and all suggestions would be greatly appreciated.
