Keep the stock air filter setup, it has superior filtering ability and our PSD only revs to 4k so you don't need more airflow at our rpms, plus, the aftermarket isn't as good at keeping dust out of the turbo!
Reliability requires monitoring for problems and fixing/upgrading the issue before it gets more expensive. Save your modding $$$ until you start watching temps, voltages, pressures, etc.
Thanks, I'm looking at getting a monitoring system that also has available tunes in it so I can mount it and keep an eye on things.
I've also looked at gauge pods, like the 2-gauge or 3-gauge a-pillar setup to accomplish the same basic thing.
I'm thinking I should maybe do both. Buy the a-pillar gauge pod, get a set of gauges, and get a monitoring and tuning system as well (Bully Dog, Banks, something similar) with a mild tune.
I don't want to go crazy. This truck is, first and foremost, a family hauling rig that will see some towing and utility use, and some usage as a daily driver, so I don't want it to be anything approaching insane power and must also maintain emissions legality, due to my need to drive it on military bases for work. I like the power that it has, but a slight bump in power, throttle response, and MPG would be welcome.
