cuts out in upper rpm and from 65-105 mph for a few seconds?

have a lb7 of a customers has efi on it from another tunner. has new injectors and cp3 in it and customer installed the rail plug him self and truck either running unloaded will cut out in the higher speeds or pulling a grade with a camper trailer on the back. waiting for him to show up to data log the truck.

Don't know why somebody would need a rail plug unless he's running some MAJOR fuel and a different rail pressure sensor. The stock LB7 rail sensor is only really good to 180, and stock valves don't pop until a bit north of 200 according to most I have heard from. Make sure the rail pressure sensor has been scaled to go beyond 180 if ANY table goes above 180, otherwise the LB7 ECm can go into a runaway and all kinds of problems can happen.

I am going to see if I can read out the tune out of the truck to see if the fuel pressure table has been touched any.

I got to data log the truck and have a data log file I am going to put up on here to see if yall see anything with it
