Hey Will, I have swapped regulators from my red Dsm and no change what so ever. I HAVEN'T done a static manual crank up of the pressure but I will to make sure the last of the 3 525 pumps is doing its job.Marty,
You might have an issue with your fuel pressure regulator not scaling with boost 1:1. Verify your diaphragm is good with a small hand pump, it should hold pressure indefinitely. Next thing I would do is solve your fuel pressure logging issue. The gage probably makes this unnecessary, but that's very handy data to have in the logs (to share with others).
What is your hanger setup? Do you have a modified stock hanger?
If fuel pressure is rising 1:1 at the rail, I would say your lean issue could be in the injector scaling.
Ill look at your log when I get home tonight. I feel your pain... Just wanna go fast!
Also, the wiring going to the Ecu is a suspect in the FP logging issue. It worked for about 2 weeks then just stopped. I think it may be ECU related as maybe ALL OF THIS is.
Thank ALL OF YOU for trying to help out the "old fart"!
