Mark, since you aren't running a modified fuel chip and you haven't shark tuned, how are you increasing your inj. pulse durations? And how do you know they are at 95%?

 

The Data logger indicates they are pegged, after this test I think I may have received the wrong ratio Fmu when I purchased the kit.
As you know I have been chasing this lean and stumbling issue since I installed the S/C kit.
For now I am waiting on Tim for his feedback, I sent an E-mail a few days ago about the chips and Afpr and this thread took me down a different road.

 

Anyone know where to get these plates for increasing the Fmu to an 8-1?

 

Any parts supplier like Jegs, Summit carry them. Open up the top nd measure the disk to see which one you have.

SUPER FUEL MANAGEMENT UNIT (SFMU)
The Super Fuel Management Unit has all of the features of the Fuel Management Unit and also features 5 separate adjustments that can be used to ''shape'' the fuel pressure curve. These 5 adjustments are:
The main spring adjusting screw
The calibration ring & disc
The vacuum screw
The optional bleed screw
The boost screw

 

I am going to install the adjustable fuel pressure regulator today. I need to remove my piping Etc any mods need to be done on the fuel lines, since its buried I would like to know if I need to chop or add new hose to it.
