Did you upgrade the wiring loom to suit the extra current draw from the second 044? It's common to see voltage fluctuations on our cars, 13-14 volts and this can have a huge effect in the fuel system and injectors. 1 Link to comment Share on other sites More sharing options...

So ~48 psi at idle iirc Edited 08/01/13 09:38 AM by IH8TOADS 1 Link to comment Share on other sites More sharing options...
