I don't mean this as a personal attack, but it seems to me like you started a thread asking for advice/information, but you're unwilling to hear what more knowledgeable people (not me) have to share with you.
I have a good understanding of the engine. The mechanical components may be able to spin to 7K.
Aint no way in hell I am downshifting at 50 mph to 4th in that car. Thats about 4,800 rpms. Thats spinning a bearing territory.
I went back as I thought you said you had the ACH...even if you have the AVX 4th gear at 50mph will be 3,200 rpm, not 4,000. AGAIN, if you tach says 4,000 at 50mph it is wrong. Even if it did, 4,000 is not anything to worry about.
Now to solve the fueling issue I talked to my local diesel guy. I will be going up there next month to work out some stuff using Cummins VE pump parts (Bosch factory stuff) to put in my pump so it will not defuel at 3,200. The goal is to have to fuel up to 5,500. That would solve the entire power problem. Why nobody has actually fixed these pumps to do that yet, is beyond me. But Cummins guys have been doing it for a long time. Think along these lines: http://www.mandhinc.net/DPD-1-F.html I may have to change out more than just those parts though. May have to end up doing some work to basically fit a 4-BT pump on the car.
The fuel pin does have to do with boost. Its not directly tied to boost though. Just in the manner that more fuel earlier = faster spool. Its the same pin the Cummins guys change to keep fueling higher RPM's.

The LDA is most certainly directly tied to boost, the only force acting on it is boost. It doesn't touch anything in the pump that in any way changes with RPM. Sent from my HTC One XL using Tapatalk

Yes 22 psi is 22 psi. It has more than enough air volume as well at higher RPM's. The K24 I had was a dog on this car. I tried to get the K14 down to 15 psi but the idiots at www.boostvalve.com will not answer their phone no matter what. I need a different spring to lower it.OK, see these engines can spin to 6K. But they start defueling at 3300 RPM. Its a inherent issue with VE pumps. So even if you can get it so spin higher its a waste essentially unless you need to go that fast. Also a huge difference between these and their gas counterparts is the cam. You will run into all sorts of fun trouble trying to spin these things much higher than 6K. And even below 6K you run into problems with fuel timing.Quote from: theman53 on April 23, 2014, 06:36:00 am I went back as I thought you said you had the ACH...even if you have the AVX 4th gear at 50mph will be 3,200 rpm, not 4,000. AGAIN, if you tach says 4,000 at 50mph it is wrong. Even if it did, 4,000 is not anything to worry about. I made an error in reporting my RPM's at 40 mph. Since my speedo is 10 off, 40 is not bad to downshift in. But 50 I will not bother to as I have no guts at that point, which is about 3300. Again my tach is pretty accurate. It has been verified with a timer.As I have said before it has no problems accelerating to about 55. Its trying to go above that, that is the huge issue. And its exactly what you need to do to pass people going slow in a 55 zone. If I had a better tranny say a ACN it would greatly improve my top end capability as I would be close to the optimum 2,800 for 60. Or if I had a 4T geared one I would have a much better 4th and 5th. Any of those would put the car in the proper powerband.Now to solve the fueling issue I talked to my local diesel guy.
