CM2350 recommendations

[Zondo956]

What is recommended for the 2350? I’ve been reading here religiously trying to do things right from the start. My driving has changed drastically!

Aside from fuel pump, egr tune up and doing oil changes according to mpg what should be done?
I have the amsoil bypass but haven’t installed it yet. Read somewhere about oil pressure so want to be sure on what to do. Do I have to add dimes to the oil pump to raise pressure first?

Now what about oil. Is adding gear lube recommended on this engine?
I would like to get it looked over by a reputable shop and get stuff done that I can’t do.

Truck is a 2016 T680 with 495,000 miles. Engine has 150,000 miles. Built November 2017. Was replaced by dealership under warranty before I purchased the truck.
