ok guys i took the leap and im gonna geterdone..i think anyway lol. ok i got an o6 dodge dually built 48re with a smarty on it . set on the tnt file it runs just a little better than my bully 140 hp setting? plus it keeps throwing p0008 i think it is fuel rail pressure too high. so i turned it back down.the reason i keep getting the code the tech at the diesel shop said its sending all that fuel to the rail and the inj cant do anything with it? im trying to learn so please be patient. he said to get the full potential with he smarty i need an air dog and some inj or nozzles which i plan on doing anyway . but im going to add a turbo too,he mentioned a turbo called a bumble bee? anyone running one. i guess my question is what would be the best quality inj nozzles and turbo that i can run . i want to run at least 100 or 90 hp nozzles as far as turbo i have no clue i want the whole setup to be somewhat reliable if thats possable? and would like something that will really make it move! thanks in advance guys!! the truck has 94000 miles on it .dont know if that matters for running nozzles?

 

DDP injectors or nozzles... havent heard of the turbo.... with 94 K on them, I would opt for a new set of injectors rather than just the nozzle. If you end up putting alot of fuel in it with a programmer and sticks, you will need to upgrade to whirly-gigger to help control EGT. Running extreme EGT can ruin your new injectors, potentially, along with the rest of the engine....
FWIW... Injector life is more accurately measured by total lifetime fuel consumed as measured by the engine ECM.
94K with no load driven by an old guy at 55 mph will burn less fuel than a teenager pulling a loaded trailer for 45K miles... hence monitoring the total fuel consumed is more accurate.
I would assume that the Cummins ECU monitors for fuel consumption...

 

94000 miles mostly idling in the parking lot texting people lol the rest running down the roads doing nothing
