I've not seen a 2 gauge kit for the steering column. I have seen people mount 1 gauge on each side of the steering column and 1 on the column. I just put 4 gauges on the A post and I'm using my MSD DashHawk (Same thing as the Edge Insight) overhead. The gauges monitor the EGT, Boost, HPOP and Fuel psi, and the DashHawk monitors the EOT, ECT, Trans Temp, Voltage on the main screen and it also monitors other PIDs on other screens. The Insight can monitor EGT and boost as well which is what I used mainly for a year or so.
