[Spoolin6.0]

I am new to forums, but after reading everything i could about injector pressure I'm at a loss and need advice.

background of truck

2006 6.0 F350
215,000 miles

major upgrades
-truck has been bulletproofed, egr delete, new heads @170k w/ARP studs

stage 2 garret 68mm turbo
fass fuel system
banks intercooler w/ high ram intake
afe stage 2 CAI
Silverline 4" turbo back exhaust
bullydog - missing a cord not working
SCT tuner w/ "stock" jody tipton tunes
-stock120 - race tune - 15mpg, fast as hell, black smoke
-stock80 - daily drive tune - hardly ever use this one.
-stock60 - tow tune - never use.

i bought this truck about a month ago because the price was appealing and it looks badass and the upgrades had me drooling. had the previous owner give me the name of his mechanic and found him, he explained the only real issue when i bought the truck.. rough idle, white smoke on idle. he said one of the cylinders was bad (low compression when cold, perfectly fine at operating temp) told me it wasn't worth the money pullig cab. i agreed. told me seafoam should clear up the smoke, so i followed suit and was happy with his advice. later i tuned the truck to the performance tune, i enjoyed the hell out of this, absolute monster around town getting 15mpg, continued to drive conservatively with the occasional WOT beating 2015 5.0s at the light. it was a blast. eventually one day had to do some highway driving and pushed it fairly hard to merge with traffic got back into town, engine light. scanned DTS found code P2290 - low injector control pressure. after an extensive google exploration of the 6.0 and low injector pressure i was confused, truck starts just fine, runs perfect, no loss of power, no smoke, i was at a loss so i tuned my truck back to stock which cleared the codes. drove some more. engine light. same code, called mechanic and he said "low injector pressure, if the truck starts and runs it tells me that its okay to keep driving but that the oil is breaking down causing the low pressure" also stated that i need 600psi to start the truck so their shouldn't be an issue. i was super happy i wasnt unloading my bank account for a new HPOP, ICP sensor, FICM. got me some rottella, changed the oil myself and cleared codes. light came back on and its been driving fine for three days with no power loss.

any ideas?
can i keep driving it without further damaging internal components?
and please excuse any mistakes i made this is my first post I've ever made on a fourm. i appreciate the help guys!

I'm taking a stab at this since the 6.0 and 7.3 both use HEUI injectors - a lot of this should cross over.

On our trucks, the low injection control pressure code is often the ICP sensor itself. It could be caused by a failing IPR. There could be, in the 6.0, an issue with the HPOP STC fitting. Then there is the pump. The pumps on our trucks are practically bulletproof. I've never heard of a rash of 6.0 pump failures so I'd have to believe they are as well. Since the sensor is a known weak spot, it would be worth swapping that. Pulling the IPR and looking for debris might be worthwhile as well. If I'm wrong on any of this, the 6.0 guru's will be by shortly to set me straight.

If it runs fine it may be the programmer. My 7.3 had an edge juice with attitude and when i would give it alot of power the truck would throw a check engine light. Mine was turbo over boost but apperantly as i understand some programmers throw codes and then go away. might be something to look at

yesterday i noticed a pretty severe loss of power.. tells me its most likely the HPOP or an HPO leak. got a quote of $2400 for HPOP $1600 HPO leak. pretty bummed, I'm thinking about getting an adrenaline HPOP to support bigger injectors down the line. anyway guys thanks for the replies, really appreciate it.

2006 its probably not an HPOP failure. More likely and STC fitting or standpipe or dummy plugs IF IT IS A HP OIL LEAK. If you are handy with a wrench you can do it yourself in weekend. Watch Dieseltechron's youtube videos on it. I did my own. I wouldn't pay someone $1600.00 to do it.

Has your truck had the "Blue Spring" fuel pressure regulator upgrade? Ther is a test port on the fuel regulator which is on the side of the secondary fuel filter housing next to the oil filter. It is a metric size for the adapter which i cannot remember, but I bought a Harbor Freight Fuel Pressure Test Kit and it came with it. Fuel pressure should not be below 45lbs. at WOT.

This is good information. I took it in yesterday to have it diagnosed and torn down. They are gonna tell me what the problem is and I will go from there. I apriciate the responses guys. Very helpful.
