I have the entire OEM fuel system only.


I only recently found out that I am running lean on the top end for sure after a 1/4 mile pull. I have known I had a rich problem down low.


I am going to find out why I am rich on the bottom end first which is either the tune or a leaking injector. I need a mechanical fuel gauge to find out if one of the injectors in leaking down and may install the OEM tune on the ECU to see if that leans it out.


Then I will need to datalog with a fuel pressure reading and IDC to start trouble shooting the top end. More than likely it is a higher volume pump and injectors that are needed, may or may not go the variable regulator route.


A big thanks as I spoke with Hustler316 and Latemodle21 about my problems and they offered very sound advice. They have both been down this road before.
