I bought the car like that I know about venting to the atmosphere. The guy put the stock injectors and turbo back on when I bought it but the afpr is still on and it has a walbro 255. That is why Im asking if fuel pressure should be the same even with a 255. Also he had a safc-2 hooked up to the car with crappy tune, if I just disconnect it will it go back to stock or do I have to do something to the safc first?
I failed emissions becaus my 95tsi was running rich. It has a walbro 255 stock injectors and a aftermarket afpr. What should my fuel pressure be at with the vac line on and off?
This is what it should be for a stock 2g4g63 but does it make a differance when I have a 255pump?
With vacum line attached:
2G turbo - 33 psi
vacum line removed:
2G turbo - 42 - 45 psi
Oh forgot to mention that when I set it to 43psi with the vac line off and put it back on it stayed around 40-41 instead of 33psi where it should be with is attached. Should I set the fuel pressure with the line connected then?
