I am running completely stock fuel system. I am reconnaissance mode right now. I want to try and figure out what problems I have right now with running rich on the bottom and then lean on the top. Bottom end rich may be leaking injector or tune that isn't quite right. I need to add a mechanical fuel pressure gauge to check for leak down and/or get the V2 program from Eurocharged to put the OEM tune back in the ECU and log again to see if it's the tune that I have.


After fixing that problem then I want to datalog fuel pressure on a dyno watching AFR for fuel pressure and see what the IDC is. I will probably add the pump first to ensure there is plenty of volume behind the injectors and then may play with an adjustable regulator but will more than likely add injectors when it's all said and done.


I've talked with Hustler316 and Latemodel21 who are very knowledgeable and took the time to share their experiences as they have been through this before.
