Despite my best intentions to not immediately turn this truck into a project, I've made several updates in the past few months while putting approximately 5,000 mostly highway miles on it.
After the word of caution from
@Tex68w on the CP4 fuel pump, my first order of business was to get the dealer to swap out the CP4 for the tried and true CP3. Thankfully there was no charge for the parts or labor under an open RAM recall. I sleep better with that potential grenade being gone.

I did some minor work swapping out front end components including the factory steering stabilizer (completely shot) with a Fox unit, and the track bar with a Carli suspension adjustable track bar. This has helped noticeably improve steering.
With the CP4 pump out, I thought I could rest easy, until I learned about a potential catastrophic issue that's caused by a bolt in the factory grid heater. Turns out that in some cases, this bolt can break off and fall into the intake manifold, ultimately dropping down into cylinder number six and wreaking havoc. After some research, I found that the
Banks Monster-Ram Air Intake System fixes this problem by eliminating the grid heater with a coil heater.
I ordered the kit, not realizing how difficult of a job it would be. What I anticipated would be a half-day install turned into a 14-hour marathon. Everything took longer than expected, but it was especially hard loosening and tightening nuts on the fuel rails for cylinders 5 and 6. They are way, way back there on this long inline 6, and very difficult to get a wrench on.

Wiring harness, throttle body, EGR valve, EGR crossover pipe, grid heater, fuel lines, and fuel rail removed for the install.

While the new system doesn't add horsepower on a stock tune, it increases airflow and throttle response, while lowering EGTs. I've enjoyed nerding out on data with my handy iDash.
