I have a ton of questions due to being a first time diesel owner. I have a 04 F350 4X4 crew cab. Here is my first of many questions I would like to add some aux gauges, I would like to have a egt and boost gauge at min. Any suggestions? Are the pillar gauges the best way to go? Or is there any other options? The truck is bone stock and I would like to do some simple mod's that are good for a daily driver. I was thinking 4" exhaust good or bad idea? I have heard many horror stories of the 6.0 being a terrible motor. I have also heard that these motor's love lots of air and to put your foot into it to keep the motor breathing freely, any truth to this? So I don't want to do anything really crazy. Like I said I drive the truck every day and pull a 24ft gooseneck livestock trailer every so often. If that helps with any suggestions on mods. Any advice or pointers for a rookie diesel owner would be great.
