Ditch it and get a dual K16 setup. The cp3's are hard to tune and all the ones i have been around have been impossible to control rail pressure at idle. Plus they sound horrific and you are limited to whos tunes you can run.

Good luck...

Best bet might be to get ahold of Haller’s Repair out of Cheyenne WYO.
I know Mike has tuned a few CP3 kits via EGR wiring on 6.4s

He finally listened and got a new tune and it works now.

Awesome!

Is there a way to test the pcv vcv on the k16 she was new truck starts idles fine but when getting on the throttle she has a lil back fire and the fuel pressure fluctuates
