N14 Celect Plus Misfire and Gray Smoke

Hey all,
I've finally had enough time to get my KW up and running. So far the issue I've had is at startup there's a ton of white smoke and an audible popping in the exhaust. The white smoke does not go away when hot and neither does the popping/miss. When I was driving it, any bad shifts made the stop engine light come on and promptly made it shut down. Tomorrow, I'm planning on checking and setting the top end tomorrow, and possibly getting in an injector harness. If the valve set doesn't get it I'm planning on disconnecting each injector to find the bad hole. As far as I can tell, there's no blowby out of the dipstick and other than the miss it doesn't feel down on power. Any other recommendations on things that could be wrong.

 

Are there any ways to diagnose between the cam and fueling issues?
I forgot to mention that the misfire and popping dissapeared with RPM and the truck gets much smoother at high idle. I think that's why I was leaning towards a fueling issue.

 

That's good news for me, it seems to have a bit more power than my other truck, but the other one is a 435hp and the KW looks like it was up-rated to 525 in the build sheet I got from the dealer. It definitely smooths out with RPM and is better by a large margin just at high idle.

I'll give that a try and see if I can get it to do it around the lot. Anyone know if the KW will only show body codes on the dash or will it also show engine codes?
Thanks all

 

Quick update, discovered that cylinder number 3 had excessive lash, but then found out that I forgot the 12 point 11mm socket I need to pull the Jake's off. I couldn't get down to the injector to feel check it though. More later.
