I have managed to sort out all of my fuel issues, but now I have a pressure issue. I am running a turbosmart genv iwg (with a 12lb spring) and a 3 port ebc solinoid (diy autotune) on an EFR 6758 and the pressure is inconsistant. I did a quick check to see if I had a leak in one of my vacuum lines but saw nothing. Any thoughts on whats going on? My tuner says its the arm, but the last tuning session the pressure was solid afaik.

 

Its a lower port bushing failure, the thing wont even hold 10psi.
