So ever since I purchased my 90 tsi I have been trying to figure out basically the same issue on my car. The car would lean out half way threw boost basically anything over 12 psi. So I started doing some digging and some logging and found out the my map readings were waaaay off. So long story short I started testing wiring going tithe map sensor. Now from my understanding it should have 5v green and red wire going in and 1.6 signal wire coming out with the key on and engine off. Well whoever wired mine up ran a 12 volt wire to it. So it was reading 3.6 with the key on and engine off. So I changed it around wired everything as it should be even traced all the wires goths ecu and checked them all against a wiring Pin out to make sure they were all correct. Went into ecmlink and made sure the correct ecu inputs were selected. But now the car won't run at all. The Only way it will run is if you set the global fuel to almost zero adjustment at which point it will start and idle barely but then go rich and stall when you touch the gas. I've even replaced the 3 bar map a new sensor to make sure that was not the issue. I don't even know where to go next. Any guidance would be very appreciated.
