I recently read in a diesel mag. If I buy a power programer, which I have already, a Intake and Exhaust. That I have to upgrade my fuel intake. I have reserched and found that buying a airdog fuel preporator and a raptor fuel pump with the Trusted Performances stage I kit and there fixed oraface kit, would give me the fuel I need. With all that how much PSI will the stock injectors take? Cause i've seen injectors cost in excess of $2800. Help me please!!!!

 

which diesel? 6 or 7.3 you should have a moderator send it down to one of those forums

 

First off, for just a tuner you don't have to get an a/m intake. Reason being is that in order for that filter to flow more then stock filter you'll have to be so far up the rpm range that you'll be long passed peak rpm for hp/tq of stock injectors that you'll receive zero benefit.

Second, you don't know all that fuel UNLESS you plan on running very harsh truck pulling competition files and ragging on it 24/7 on the street and then you can say bye-bye to headgaskets, hello headstuds.

Now what your injectors could use is an ITP fuel Regulated Return kit as that would remove the dead-heading issues that are common on the 6.0s(I'm basing this off your profile) and it will increase fuel pressure to the stock injectors as well. An airdog system just isn't needed at this stage.

That $2,800 for injectors is also out there. You can get Stage III injectors for less then that and that will be more then enough power for the street, unless your making all this for an all-out competition truck and totally unstreetable because Stage III injectors is about as high as I would go and have it still have street manners.

I don't know why the article mentioned what it did unless I'm able to read the article, might be something that is missing, but there is no way that you need that kit just running a tuner as your power enhancer. Don't get the intake, you won't get much benefit(if any at all) at this stage of the game, exhaust will help. RR kit will help you the most at this stage and besides that, even if you do decide to go for more hp you'll need the RR kit anyway later on down the road as well.
