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.

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

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.
