twin tuning help needed

Boy Id love to be wrong again lol.. Ill have to check when I get it back.. DL thinks its fpr voltage settings incorrect..i would think a stock tune would haul ass with the combo and 60 plus % over sock injectors. they boasted that it runs "HARD" go take it for a spin.. Makes HUGE black clouds then cleans up and runs no stronger than my tt gt45 over stock LB7. It should spool up and roast the tires. needless to say i was NOT Impressed....
I have a shit tonn going on atm. We are buying a house. Took a while to find one.. Now we are packing and getting ready to move.. On top of that Both my other dmaxes have LRP codes.. Lol dually not happy to pull 44 foot 5th wheel .. servic truck is pissing fuel from some where in the valley.. trying to get those done after 3 hip surgerys is Fokked.. Yay (Sepsis) in jan put me down 6 months... Went from 238 lbs to 170 in a month....im back up to 218 ....I cant seem to get more than one solid day in and need 2 days rest =(
I see you guys been busy looking at my shit. I APPRECIATE ALL OF IT....... Ill be hit or miss to see what your guys thoughts are.. thanks again..
Maybe Next year I can finish the Camaro lol

i fear logs might not get me enough info. Ill see if Steve is willing to look at it. To be honest though, if Josh is willing to look at it, id go to him in a heart beat. Josh has done some really cool things and fixed some very interesting problems before. i would bet he can lick the issue or atleast tell you where the issue is if its a hard part. im 50/50 from what im reading/seeing that its either tune or hard part combo issue.
I got no problem admitting if I can't get it figured out, but I'm more than willing to take a shot at it.
That's who he had do it. I'm sure it's a hard part issue
Just FYI guys, due to the epa, danville is no longer tuning or building turbos... The powers that be pull the rug out from under mark, sadly. @MarkBroviak can probably answer more on this but thats why Danville is no longer a sponsor here.
It now hold 28 k rail pressure they said. so its not injectors? its not cp3s? sould not be fuel labs 200 pump. I need to see again but im pretty sure I ran 5/8 or 7/8 feed line to pump and from pump to cp3 off a sump....
Yes Broviak tuned it at least 8 revisions... Unfortunately he was very difficult to work with =( I could not get phone time and days to respond in an email was ver frustraiting and id get tune revision with "here ya go try this out" each time making less power. At least where its at now they have it pretty responsive in dsp1... when im done at this next place ill have spent about 1500 in tuning... the first tuner I dont think changed mt gear ratio from 373 to 456.. I have abs light and brake light on. I bet its the abs ecm speed correlation. ill check it when I get it back w Tec2win...
Soooo.... update. I got a call from the place its at. he said "its running good on tune 1". no smoke and responsive.. "come drive it, its fun now"... Im sad to report and happy too. dsp 1 is responsive but very light smoke in rvm... backing it in their stall i could see it wafting a black puff here and there no throttle added.. would not really do much when power braking it on the test drive. it did not change when switching dsp in that process. nor did it do anything wot moving down the road either.. he said "its showing in the pids as working" Asked me to come drive it in the morning cold.. So my test drive went like shit. maybe makes 500 rwhp..
F M L ... lol
He got 28 k rail and it held while fishtailing through third and had to let out.. so again. I dont feel its a pump or injector issue
Odd part he said.. "After re-flashing it, It would go into reduced power mode with no codes and clear with key cycle".. ???
Hes wondering what os the tcm is.. its locked by danville. it also downshifts to first VERY hard coming to a stop sometimes (50% of the time )and always has... Tuning????
Hes wondering if tcm is de-fuling it in a limp of some sort... This is a dual tank cab chassis tune...Also says they can do wierd shit... but tried a standard file..
To add to my misery my 07 dually pops a low rp code and limps pulling my 44 foot toy hauler. AND my 13 svc truck pulling my 66 chevelle I bought back from texas poped one too the last 100 miles about a year ago, and as of last week poped the return hose pissing diesel out of the valley... Im inn the process of doing 2 cp3s on 2 trucks right now. 13 is a conversion both have lift pumps. svc truck got a fuel labs on day 1.. dually got air dawg before i tried the trip because it popped the code last year omw back from the dunes ol

What parts do you guess?? it aint fuel pumps nor injectors if it holds 28k psi while sideways in 3rd???? and it wouldn't get over its own dick b4 this last revision...
Not trying to be a dick. But you say everything mechanical is fine. You think it’s a tuning problem and multiple tuners can’t fix it. Tuning isn’t magic. A factory tune should be drivable with 67% injectors. The entire truck needs to be gone over.
Check for boost and exhaust leaks.
Make sure the turbos are good.
compression test just because.
Check to see if the injectors are leaking while cranking and the truck is disabled from starting
After that you’re left with fuel, if rail is holding the pumps are fine.
I’m still questioning the injectors, I would have them sent out. Hell for how much you have into retuning you could have almost bought another set.
Nothing really else to check unless I’m missing something. All of these things need to be checked, if they were checked a year or a month ago isn’t good enough for me they need to all be checked by one person to make sure nothing was overlooked.

Your not being a dick lol.. This tuner HAS made progress.. you see now he has it spooling like it should with just tuning alone. that log file dropping rail pressure? it was fixed with tuning allone
Hey now,,,, Im one person...yep I am not perfect I like to think i am though lol

some of it. re read my ramblings.. its all in there.. not making consistent tire shredding power yet..Im going over w my laptop in the morning.. im gonna log it my self and post the file.. Any pid list preferred?
If i can get what fixed it Id love to post it. it would be nice for everyone reading to have this one in their tool box of W T F....
The custom tune I got from Danville did nothing to change anything. I tap shift this truck at 5200, Ironicly tapshift is not functioning now I put it in m and it changes nothing on the dic. I will diag it soon.. It does not wot high rpm shifts in tow haul nor normal..Im omw to the labritory now to go work with them on some of these issues
Interesting. Being a VGT I doubt there's much power to be made at 5200rpm compared to bringing the RPM back into a more reasonable range for that itty bitty turbine.
