What gauges would you get with boost?

In preparation for the supercharger install, I'm planning to install an A-pillar gauge pod (if I can find one) with three gauge cutouts.

I'm obviously going to be installing a AFR gauge for the wideband, as well as a boost gauge. For the third gauge though, I'm curious if there's anything else that would be ideal to monitor?
 
That is a great question. Of the 4 currently displayed in the instrument cluster that is Fuel, Charging, Oil Pressure, and Coolant Temp I would ask which of the 4 is most important should something happen where early warning would be most valuable. To that IDK but I suppose of the 4 coolant temp and oil pressure would be most important with oil pressure being most important since there is a bit of cushion in the operating temp ban that does not exist to the same degree with oil pressure.

You could always get a 4 gauge pod (good luck with that) and monitor both coolant and oil. But 3 seems to be the limit and even that is not specific to the TJ.

If you were to run an air to water intercooler you can monitor its effectiveness. Also, if you are running a hot enough tune, high IAT's can cause detonation.

Very true. And my supercharger is running a water-to-air aftercooler setup in order to keep the manifold temps down, so an IAT gauge would actually be of value.

A wide band sensor is good for tuning, beyond that, it won't have a long service life if it's installed all the time. What I found useful was an OBDII plug-in for my computer. I would log performance events and analyze later. I considered real-time monitoring a distraction. When a tune has a healthy margin of safety, gauges beyond the basics that are already on the dash, are not necessities.

A water-to-air will saturate, that's just the way it is. Great short term, long term so-so.
 
The wideband is invaluable for diagnostics in the future, and you know if it's running right! Never take it off with boost.

Where is your IAT on your kit? Mine is in my air/water aftercooler so I can look at my PID's from my PCM and see the IAT's using the Torque app. It'd be cool to have another IAT gauge setup before it hits the blower so you can calculate the delta and know the effectiveness of your cooler.

Don't get a boost gauge, get a boost/vacuum gauge.
Don't get an EGT gauge. You really don't want to know how hot that shit gets, it is downright scary. Get an intake air temp gauge.

Put one on a TJ stock and watch it. Take about 2 days and you will remove it or tape over it. Some shit we don't need to know.

I’ll take info and remember it, thank you. Ya it’s not bad on a diesel but I have 0 experience with the application on hand. I’ll just keep watching

17-1800 degrees was common. Based on the one in my diesel, I quit looking at it because (a), that is a scary number and (b) without a reference, it may as well be a pinwheel stuck on the front fender that I watch turn in the wind as we go down the road. As in, is that really a scary number? It is too hot, not hot enough, or just right?

And to clarify when I say 0 experience with the application I meen with the 4.0 intopic.

1700 to 1800 to me would be to high. But thats me. My gauge maxes at 1600.

I typically run between 1000-1300 pulling a load up hill, I always try to stay under 1400. (5.9 CTD). When I was saying driving by the gauge. If the EGTs were getting high, down shift bring the boost up and the EGTs will drop. But that’s my experience with diesel and I’m betting it’s is different with a supercharged 4.0.

I have the same motor, same gauge, and same rules, so I did understand.
