Hi I'm new on here and need some help. I converted my mfi over to efi and can get it to start and idle ok but if I try to rev it it just sounds like it's dying!! If I really slowly try to rev it does but sounds like it's revving twice as much as it should. I have changed leads. Plugs. Cps. Map sensor. Checked all connections on sensors and Ecu etc. It's running ofab setup and just folded back old loom. Also the Rev counter isn't working I have changed it to pin 11 on the edis and still no joy any ideas??? Also what fuel pressure should I be running it at??
