I've looked into them. I don't want anything radical

They can just make your truck have more power, fuel economy, better shifts, add efans etc.

Well I thought the service and new fuel and air filter solved my issue but nope. Still there and it's not throwing any codes. In thinking of tuning it up next week

Plan on it next weekend. It's more of a stumble but only happens when I start it up and take off

Probably is dirty plugs, it doesn't do it if you let the truck run a minute before driving?

It came up with three actually:
P0137
P0157
P0300

P0137 is O2 sensor bank 1 sensor 2

PO157 is 02 sensor bank 2 sensor 2

PO300 is random misfire probably caused by the 02 sensors sending bad signal to the computer

my PO300 random misfire was that the plugs had about .180 gap. worn out plugs had about 200,000 mile them from what it looked like

Should I put anti seize on the plugs when I replace them

Absolutely, it's a must, I've heard of people snapping spark plugs off cuz of no antisieze

That's what I figured seeing as its an all aluminum motor. $45 for plugs with a $10 off coupon

New plugs and wires and I still have a stumble. What's next?
