what a gentlemen:spit:
And thanks for the info i didnt want to get my sensitive skin all cold and shit
Ha your welcome. That's from my lbz, but would imagine all duramaxs run around that at idle.

LLY: 85 over cp3. Sounds like a ford

Albert just thinking out loud but it might actually go fuel rail but just take a bit to do so?
Not sure....thats why i asked for a log file.
Pat, Tony could fix this he is a really good tuner and knows his way around modded D-maxes.....Obviously you dont want to drive there to find out its not tuning but it might just save a lot of head ache
Yea I know. But he is nowhere even remotely close to me. When I got it tuned initially, I lived close to guy. So it was easy. But I don't live close to him anymore either.
Personally from what ive read on a few other trucks with ii 85% over pumps, ive not seen them hold rail for 60% over sticks and that high a rail pressure. The threads ive read have been very far and few between though so maybe its just certain pumps? Tryin to think positive but I dont think their 85% over pumps really pump out that much more volume than stock.

Ahh, I got ya. Your thinking its getting there just taking its sweet ass time (pun intended):hug:
Yea so far this thing flows about 85% less than stock. Maybe that's what they meant by "modded pump"

I am not here to bash any product, from my experience in these situations I believe there is a little bit of hype on modified pumps.
85%......what does that mean ??? does it mean it will flow 85% more fuel ??? does it mean the regulator triangle is 85% larger ??? does it mean the pump internal holes/passages are 85% larger in diameter ???
I have tuned many, many trucks over the last six years, even stock trucks will act differently with the same tune as no two trucks are the same.
There are old school ways to keep rail psi up with a single pump, they can be activated with either a HOBBS switch or a DSP-output, but those are usually for pulling truck in the work stock class or a 2.6 class/single pump.
Pat,
I assume you were logging only the big tune, the smaller tunes may have held rail psi fine, in my experience a big tune that holds at least 19K-20K psi will usually make great power, you don't have to have 26K psi to make power, for example, my LB7 with a single stock LBZ/CP3 makes 518 "REAL HP" not a rigged dyno number from (hint-hint-hint) a certain midwest shop.......and will run 12.6's in the 1/4 mile only holding 18.5-19.2K psi.
If I travel to NC in the spring I go thru VA, depending on the distance from VA to NC it may be closer to you for tuning.

I understand where you are coming from tony. If I could do it over, I would just go with duals. My stock pump was so weak and worn, I just wanted it out of the truck before I got stranded.
I'm really shooting for 11's in this truck. The cp3 is what has been holding me back. I finally got a new one and it's STILL holding me back. That's why I don't want to accept the 19-20k Rp.
Well that and the fact that I bought a product advertised to do something that it can't.
I see your point there, buying a product which is NOT performing for you.. If i were you, i would call II and be like you either make good and send me a new product or else. Say you have logs to prove that it is not up to par. Tell them your whole situation, and don't take "well i don't know what i can do to help you" for an answer. Thats what i would do. :thumb:
When I was having problems with my cp3 I called ii and pretended i had one of there products.. just to see what they though could be wrong with the pump. It couldn't hold any rail pressure, but I didn't know why. It was only holding around 20,000 aswell, and would slowly slowly run up to about 24000 with the fca unplugged at idle. Anyways they really don't know what they are talking about, even though I was talking to a tech. He told me I need bigger injectors, and than I would get full pressure. Which is the stupidest thing I have ever heard. That's industrial for you

Hahahahaha HOLY SHIT!
I'm gonna call them again tomorrow (if they are open with it being Sunday) and talk to them about the whole fpr idea. Y'all are right. If it was stuck, it wouldn't go to 26k+ with it disconnected. It would have just stayed at whatever psi it was at when disconnected. I'm thinking a refund is in order.
After hearing their "tech" say it is a fpr issue i would have stopped them right their. Did you purchase it directly from II?
Well they actually said "FCA" lol
But I bought it through Ryan Thacker of Gardena auto parts. He is a SoCal diesel trucks guy.
There 85% over pump cant even fuel my 45% overs i gained 1000 psi from my 244k miles lb7 pump to a new 85% over pump (17k up to 18k). Brady said that "he couldnt believe his guys sold a small pump for big nozzles" those are his exact words. He was willing to give me a deal on a 120% pump but a ppe twin cp3 kit went on instead. I also used my old pump in the twin cp3 kit with there modded pump so we'll see how there pump lasts.

Do you reread your post? Not trying to be a dick, I'm really asking. You always leave words out or misspell and its hard to understand what your saying.
