LB7: 1093/1094

[LB7Diesel]

Got a friend of a friend that has a max of 7K RP. I did a log of the truck and it's commanding 23K but actual will not go above 7K. I didn't have a chance to look at rail current yet, so I wanted to see what you guy's thought it could be. CP3 or FCA?

 

[LarryJewell]

could be either, unless he made a big error in tuning, is he using efi

How many miles on it and what power adders

Try unplugging the cp3 pump and see what it does and what about the fuel filter

Quadzilla 135tune. RP doesn't respond with a stock file either. Fuel filter was just changed. I didn't unplug the fca it was to hot and it's a bitch to try and get too. Just fig I'd throw it out there and see what everyone's thought's were. The 1094 was kinda weird I thought?

That's what I was thinking since the pump won't make shit for RP.. FCA prob stuck.
