Mfabsr20 is an unknown quantity at this point
I did that also. I would lower fuel pressure in increments trying to find that "sweet spot". Thinking that I would be out matching the fuel pump. The same would happen, the car starts to sputter then die. After going over my engine a few more times, I am starting to believe the isis fuel pressure regulator is just crap.
