Title: 650cc injectors 2002 Audi A4 Quattro 1.8t Post by: 2002b6guy on January 19, 2017, 08:55:54 PM Hey guys I am having some problems with tuning these injectors I can get it to idle but I am running really rich. Does anyone have any suggestions? I have changed KRKTE TO .06 and have adjusted tvub. This car is returnless fuel system and I think that's what is causing it. Let me know thanks
