Default monitor or ??

So, bought my first Duramax this year (don't know what took me so long) and I love it. I took it in for it's first service this week and had an issue I brought up with the guys at the dealership. Most of the time I get ~22mpg on this highway I travel. Occasionally, it goes down to about 13mpg on the same road, same speed. I brought it up at the service dept and the guy gave me a generic answer.."well, there are a lot of factors that go into the mpg display" I could tell I wasn't getting anywhere with this guy. So researching I found out it's normal and it's the Regen system doing what it does.
Now, my question is: is there an easily installed, non-intrusive guage that I can get that will cycle between boost, egt... Just to monitor what is going on, without manipulating the ECU?

That looks like what I want. The website was pretty vague. Does the unit come with everything I need, or do I need to buy additional cables for it?

I kinda like the banks idash super gauge. But I don’t really care for the big screen monitors.

Yeah the CTS2 come with everything for install. Just plugs into your OBD 2 port. Nothing to it

The L5P already has a manifold EGT sensor that the CTS2 will read.
