After putting in a modified CP3 pump in my truck I am throwing a P0088 code high fuel rail pressure! as well as P0089 fuel pressure regulator performance code! I got efi_live I need to know where to go to adjust for the higher pressures.
 
I Believe if your pressures are higher than what your looking for table B1010 should help. you may have to add current to lessen the flow from the regulator.i'm not totally familiar with the LB7 tables but from a quick glance I think thats the place to start.
 
Thanks for the info. I will try it out and see what happens! There are a ton of adjustments with the efi live its hard to get used to it, but sure am loving it
