Anyone using them. Info on site looks promising. I am just trying to max out stock system before making the big jump.

Elite has the same stuff available...even the same description.
What's the VCV- Volume Control Valve?? Does changing this mean the tuning has to change to account for the modification, or is it just the addition of more volume?

Did you order both the rails and the VCV or just the VCV?

WHY NOT

Are you planning on a before and after dyno with the mods you are adding? I am interested to see how it turns out with what you are doing with your combination of mods. It will be neat to see the WW on a deleted truck as well.

I'm also interested in seeing before and after dyno results!

For right now will just be seat of the pants. I assume there are good enough numbers for the before condition. Would like to do the after setup at some point.

Every truck seems to run different I've seen anywhere from 450-510. One major thing to watch though is boost and back pressure when installing the WW2. Make sure you take some pics and put them up with the instal as well.

Are you having trouble holding rail pressure now at full throttle?

15k is what I see right now on an isspro guage. I can't comment if good or bad, but seems low?

Anyone know how much more that modified VCV will flow over stock? Also is that all Industrial Injection did to get their 33 and 55% over pumps?
I would guess at wot you are commanding 29k.
However the issapro guages are setup for a cp3 system and sensor.
The voltage varies between the 2 systems.
Lml duramax and ford 6.7 read 15k on that guage and rail is actually 29k.
I think you are holding rail fine.
Add fuel until rail falls off. Then install ported rails and modded reg and if you hold rail they are working!
No they stroked the cam.
I tried modding a regulator or 2 and did not getany huge gains. It did help.
I also just gave up and went to twin hpfp's.
I am sure with the rails it will help, or else they would not be selling them!
