I am kinda new to remote tuning and I want to understand my datalogs a lot better so I can communicate with my tuner. My setup is 03 cobra, snakebit ported eaton, 60lb injectors, KB BAP 20amp with upgraded wiring setup, SCT 3000 Maf. I have been told you never want your Pressure Drop from Injector to drop below 39. I understand why you should never see under 39 across the injector but what I don't understand is the sudden increase and drop within 100 rpms while WOT. For instance my datalog reads 4516 RPM, FPDC .373, and FPFI at 37.47. Then @4584 RPM, FPDC .382 my FPFI is 39.97. It seems my pumps are effecient enough to produce 39 psi at any given rpm. So why the fluctuation in fuel pressure. Any help?
