Do those that have installed boost and EGT gauges on a truck with aftermarket turbo find them useful long-term after initial install and tuning?

Even if you never play with your tune it makes identifying engine issues much easier. I first noticed a head gasket leak once when my cruise egt went up 75 degrees. I would never drive without egt and boost gauge and mechanical coolant temp gauge and mechanical oil pressure gauge and an altimeter and a......

Yes, especially when doing different things like hauling a 3000+ pound trailer over a 6000' mountain pass in winter...and keeping an eye on the EGTs. Things like that let you know if you are still running a safe temp, and that additional loads can definitely heat things up quicker and higher than normal operation.

All of the above, And don't forget, they increase your manly manliness, and sex appeal. Ladies love gauges.**

EGT gauge is absolute necessity if your fuel is turned up to take advantage of the turbo. Especially if you live in the mountains.
Boost gauge, maybe not so much. But apparently it impresses the ladies, so I've left it in place.

The boost gauge is basically eye candy however in my humble opinion the pyrometer is a must even on normally aspirated Diesel engines.
I learned my turbo needed a rebuild due to boost gauge. Started noticing I was losing boost on my normal commute. I watch boost and EGT gauge constanly. EGT is helpful when shutting down the vehicle. I usually wait until EGTs go down to about 300 degrees before shutting engine down.

I could not live without boost and egt gauges in a diesel vehicle. Definitely not something you'd regret doing. Well worth the money.
I have a redarc boost / EGT / coolant temp gauge (all in the 1 gauge), and generally only look at this, my fuel gauge, and speedo. The boost gauge has picked up a boost line that popped off that I wouldn’t have otherwise noticed (apart from no green light), and when towing my boat in hot weather I pretty much drive to the egt and coolant temp....
In short - yes, they are worth it long-term...

Ever driven a new car? The only gauges they have are speed, fuel and tach. These diesels also never came with pyrometers or boost gauges from the factory, and most have been on the road for 25 years with no issues.
If your engine is tuned to run properly and safely, no real need for extra gauges in my opinion.
If you are wanting to change aspects of how the engine runs, notice the changes, run it to its limit and want to look cool, then gauges are a must.

What type of EGT sensors do you guys use? The kind which just has a simple metal attached to the exhaust manifold? Or some kind that has a filer in the air stream?
Any examples would be appreciated because I don't know how to seperate the wrong from the right.

You want the EGT probe in the exhaust stream, so you're measuring the exhaust gas temp, not the temp of the manifold. You want the probe pre-turbo as the temp drop across the turbo is not linear, and can't be extrapolated without having a probe pre and post turbo to compare, as it will be different from application to application as well.
Dork seems to be missing the point. We don't drive new cars. Our 30 year old trucks are modified. If you are running a turbo on a 3B, specially one that is less than professionally engineered, you best have gauges to inform you what is happening. Overheating in the EGT department happens very quickly. The pryo is the warning to let off before its too late.

Sometimes the manufacturers get it wrong. There's been no shortage of early 2000's Nissan patrols in Australia with the zd30, 3litre turbo diesel engine go pop due to fueling and boost related issues when in standard trim.
The zd30 engine is refereed to as the hand grenade by some people, it was such a problem.
EGT gauges probably would have highlighted the problem.
Fair enough, but that is just one example out of millions of vehicles out there on the roads worldwide. Those odds are good enough for me to believe the manufacturers in most cases.
Again, I am strictly talking about driving a vehicle in its straight from the factory form. Make changes to a vehicle and all bets are off.
