I have an early 2004 common rail with 105000 miles. Has a smarty s06, airdog 150, isspro ev2 gauges, S&B intake, custom intake horn, and the bag of parts done to the cp3. When I bought the truck it had the code on it and so I clear it with the smarty and now the code won't stop popping up even at idle sometimes. I have 7k psi at the rail and 12-14psi supply at idle. Cruising at 65-70mph 2000-2200 rpm I can maybe get 14k psi at rail and 10psi supply. At wot rp drops to 10-12k psi and supply stays the same. Someone please help before I start blowing money where I dont need too. And other things I need to watch out for on this truck please let me know. Thanks in advance
 
Yes stock injectors and any level on smarty and even set the thing down to stock to see if that changed it.
