So I have a banks economind. But no egt probe. I don't do much heavy pulling. Do I need the egt probe for the tuner to work? Any concerns with not having the egt probe? I'll likely only run on economy setting as don't really need much more power than that.

What about the boost Guage. Do I need that?

more gauges are usually just cheap insurance to keep a close eye on your trucks health, are they always necessary no, are most of the mods any of us do necessary no, some trucks run plain stock for hundreds of 1000's of miles, but once you add power its always a good idea to keep closer check on trans temp, egts, and the like
