Well, the new camshaft grind may not be compatible with the current tune, whatever that might be.  You have a lot of unkowns under the hood and the tuner can help sort them out.  Might not be the tune at all, could be a bad MAP sensor or MAF sensor or throttle body or a vacuum leak...

Ok I pulled the first plug on the driver side and it has very little oil just past the nut. I'm gonna pull the rest and see where I'm at. Or I'm hoping it's just a leak down from the valve cover.

 

Update. I pulled the plugs on the passenger side and there is no oil on them at all and the valve cover on that side is not leaking either. Hopefully that's what the reason for the condition of the plugs on the driver side

That plug looked pretty ratty for being in a fresh motor.  What is the part number on them?

Acdelco 12621258. I put in Bosch double iridium plugs. Bout to start it up now. Started right up, drove it around and it's running so much better and smoother. Hopefully it stays this way.

They were the right number but looked old and wore out.  Sounds good, keep us posted.

Just a final update.... even though the truck needed the tune-up the whole rpm dropping and raising when braking was still present. I ended up changing my tps today and it runs like a totally different truck. No more issues at all.

If I can save someone the trouble when they search these threads, then my headache was well worth it.
