I've got an aftermarket fuel reg but when it was installed they left the standard one plumbed in as well, but i just want my aftermarket reg to control the pressure. I'm told i can just disconnect the vacuum supply to it and that will disable it? Just want to double check before i do it.

It will disable it, but the pressure will stay pegged at 43psi, and will not go below this. Best thing to do is set a base pressure of ~50psi on the new reg, so that when under vacuum the pressure will drop accordingly. However you will need to adjust the fueling to suit.

      R32 GTS (RB20DE) Injectors Replacement

      The issue now is the 'fuel cut' while driving, and when it happend, it does not stall. This, I did not test the fuel pressure while driving as I cannot with a fuel pressure gauge. I do have Nistune logs, yes. I have also replaced the MAF Sensor.   Also related to the FPG Fuel Hanger – I just realized that I need a Deutsch Crimp Tool to crimp some cables for the FPG Fuel Hanger. Need to purchase additional cables as the kit only included 2, which are for the float. FPG has not responded to my emails so far since purchasing. I thought about taking it to someone and having it done professionally, but I am reluctant since everyone I took it to messed up in some way.

      The German place in Cabramatta was rock solid, fresh pretzel cooked to order back then. Then it went all quiet, after all the poker machines were removed, then I believe it closed for good. I did drive past the other week and noticed outdoor lighting a big screen, but no idea what is there now.

      Yeah I suspect even if you hold airmass per cycle/cylinder constant if you get too far away from stock you're still going to have problems running the factory tune within the bounds of the factory load scale. Cams, different displacement/rod ratio, etc. I'm just lucky that the GTIII-SS with wastegate boost + CA compliance cats is pretty much equivalent to stock turbos. When I have actual space I can finally get it tuned and modify the fuel system for flex fuel to 100% handle any detonation concerns when cranking the boost to whatever those dinky turbos can put out.

      I would say no, why, because my daughter, who also lives in Goulburn, hasn't recommended us going there Pity, as we miss all the German joints around in Sydney, actually, the restaurants are the only thing I really miss about Sydney, and a special mention to Ishibanboshi at Bondi Junction, their Kara-age Don is heart cloggingly deliciousness (always added a special boiled egg...or 2) 😋
