N75H valve, chipped, diodes, overboosting??
Hi,
I have a 98 Audi A4 1.8T Quattro (not drive by wire, Australian model), it's chipped by APR.I'mlooking at fitting new diverter valve.
regarding the Bosch valves; N75J and N75H, I read the H version can give upto 3 psi more however I also read info regarding too much boost causing limp mode, hence being safer to go with N75J. I also read about diode mods to trick ECU to think not overboosting.
Basically is it possible to run the N75H valve on a chipped (Australian) Audi possibly with diode mod -without overboosting and going into limp mode?
