Any Codes on the truck? It sounds like an IPR issue, if the nut was loosened while they were under the hood it will cause run ability issues. What brand CPS did you use? Was it a Ford or like an Autozone/ O'rileys?

If you can get a scan tool look at your ICP duty cycle, it will be a percentage and look at your ICP PSI. Also try and get a fuel pressure gauge hooked up to your fuel bowl too see what pressures you are seeing.
