troubleshooting issues
2013 F250 powertstroke. 170k replaced a couple injectors and fully deleted.
About 1 year ago heard a pop while under load (pulling 8k trailer) truck started to smoke bad and run super ruff. I put in some fuel additive and after a few hundred miles it was back to good for about a year. A week ago another pop and truck ran like crap like it couldn't get fuel. Tuner started to log codes on almost every cylinder for cylinder contribution problems. First thing I did was a relative compression test and it showed no signs of problems. I figured I got hit with the cp4 fuel pump trashing my fuel system. I just pulled the fuel pump regulator thing and I have no signs of metal in the system. So now I dont know where my problem could be. If its not a fuel problem should I check the heads next?

I am only getting cylinder contribution codes for 1,2,5,7,8 no other codes.
I spoke with the tuner and he said he would bet it was cp4 failure and contamination. I have a ez-lynk2 and send him a diag log and he could detect the problems but that was about it.

Over the weekend I installed a cp4 disaster prevention kit since I didn't see any signs of metal in the fuel pump regulator area. I figured I was already here so why not? Drove the truck around a few times in the last two days and now I have some codes to work with. Runs very ruff and I think im done driving it now until I can get it to a shop or something.

Im still leaning on that its prob some fuel related problem. Any idea/input.
Thank for any and all help.

Sounds like the disater prevention kit is starving your engine cause contribution problems and misfires.

Its running the same as before the disaster prevention kit was installed. Sorry for the confusion.
Also my commanded fuel rail pressure and actual fuel rail pressure matches so Im thinking I can't have a huge clog or anything? (yet?)
But this link you sent is magic. I'm printing out now.
