Thanks for the specs!! Ordering a complete set of inj mon from bbi.

Found it!! #1 harness grounded to each other. and to one of #2 wires!!

Ok guys. Need info quick!! I took valve cover off. Checked voltage at injector and at harness connector. 1,2,3 voltage 11 to 12. 4,5,6 17 to 18. Tested while under load( power brake) all injectors increased voltage as supposed to but still had the 6 to 7 volt spread. Whats going on? Is this normal? Checked valve cover seal inj harness all has same ohms. All Inj post to post is 1.5 to 1.6 ohm.

Good advise. Thanks. Maybe twins in my future also.

Read thats 06-07 5.9 op temps are 1100-1400 egt. If so mine is in range. Still dont like it that higher. Looks as if my bigger turbo did nothing for lowering temps.

Egt 200-300 at idle. I do have an ir. i will get readings 2moro and post findings. I know by guage tuner if its say 1000 at cruise and i let off it drops as one would expect. I will take ind cyl temps and post also.

Pyro goes thry bullydog gt. assumed it is right. Guess time to get some manual guages.

Called the place i bought my kit from. They assured me it was for 07 5.9. I didnt check casting numbers during rebuild but visually looked as the stocks did. Had to go i cant remember 10 or 20 over to clean up walls but nothing else as far as dome or bowl top. All looked same.

Im with you tom. Im thinking of doing a set and a new cp3.

Im jealous!! Lol. I believe when i can get this fuel issue solved and do some programming with efi live i believe my dormant monster will come alive.

I would love to see my egt around there. Another reason that points to faulty injectors. I have no excessive smoke. Im burning clean. Haze at first but clears up quick. Was like that b4 rebuild tho too.

It is constant at 20% at any range as long as its under load. In park cant detect it. 20% per guage tuner Temps not known before rebuild. Added egt guage during rebuild. If i set cruise at 85 instead of 75 temps run 900 to 1000. 46# boost wot, 14 to 18 during pop. Cam is journaled. Thought josh told me they were 160s. Might have misunderstood.

Thank you!!

Where is he located? I appreciate the info!!

Efi live is definately coming in the very near future. Wanted to try to solve drivability prob before going to reprogramming. I know the efi will help with that also. Looks like i need to get one asap. Any suggestions as to the best deal on a flashscan??

Im sorry i wasnt more clear. The injectors were replaced before the engine needed the rebuild. Thats the only reason why it didnt have improved sticks. If i knew it was going to have to be rebuilt at the time the inj needed changing i would have but wishful thinking was to just replace stock with stock inj and drive it another 100-200k. So where would you recommend me purchasing a 50-100 hp set of sticks from? I dont want to use anyone around here. Seems like the quality isnt a high priority for shops around here. Just make a quick buck.

Rebuilt was supposed to be by auth bosch shop in houston thru the people i bought from.

Did injectors at 200k and rebuild at 214k. Didnt want to do anything out of the norm at 200 but then bloyby kicked in one evening and found #1&6 fire and comp ring broke.

Thanks guys. No harm no foul!! I was thinking on same line as both of you but i did have one shop w/efi live hook to it and he said everything looked normal. Fca is new and i even went to the length of putting a new stock in place of the modded one but no difference. This truck has been to different shops and all say they dont understand y and especially at just the 20% throttle mark. I do know that is where cummins fuel pressure demand is cut for supposedly better fuel mileage at cruising speeds. Also please note. I try to make mods compliment other mods. All has been documented manually. Mpg never seen an increase on any mod until cp3 was modded. Seen a 2.5 to 3 mpg for the better. Strange i know.

Excuse me but i was talking more of auto stealerships not my holt cat. Heavy end compared to light duty are two totally different worlds but people some are just part of the masses. Although all are allowed the freedom of speech sometimes silence protects the masses from being thought of in a negative light. Thanks for all the great points and suggestions. All will be tried and reported back on.

My cat truck shop said they cannot communicate since dodge writes the programs. Dont know if thats true but cummins southern plains in dallas told me the same thing. I hate stealerships!! Rail pressure and supply pressure holds steady through the event. I may have overlooked but i did examine the harness closely during the rebuild. Acts like air in the system but if so its going to have to be either cp3, fuel rail, crosstubes, or injectors. Everything else is new and verified not to be leaking or sucking air.

Yes sir i did. I replaced them 8 months before i did the rebuild. Had them tested by a bosch auth shop in houston. I took them back where i bought and they sent them there. I wanted to have them tested since i was doing an out of frame rebuild with mods. My shop said they tested within spec to run them. Guess maybe i should have gotten a 2nd opinion.

I drove today and watched the rpms. You were right. At cruising speeds 20% throttle is around 1700. It does it at all gear ranges at 20% tho so thats where i meant it happens at diff ranges. Thanks again.

Does with or w/o bullydog. 1000 to 1300rpm. Somedays better some worse where somedays you can actually feel the truck jerk when the pop/miss occurs.

Im a newbie!! Frank from texas. 07 mega 4x4 dually 5.9 cummins, fresh rebuild, arson kit cp3, rebuilt stock sticks, new tank pump, frame mounted 2micron filter, new map sensors, 63/68/14mm turbo, hamilton 210/188 cam, 160# springs, built 48re, new tps, bullydog gt usually ran on performance to help spool. Pop/miss at 20% throttle. Has done this forever. Even b4 rebuild. Have replaced everything and done everything i can think off. I am missing something tho. I am a field tech for caterpillar and this cummins has me stumbed. Also egts run high. 1000-1400 at cruising speeds. Love my truck but getting to my witts end on this and dont know what else to do. Oh and put a new ecm and updated flash program from dodge to see if it made any diff. None. AND truck only and has always since i have had it 12 to 13 mpg on highway and 11 to 12 city mpg. 5000# load to houston, 8to 9 mpg. HELP PLEASE!!!
