If you are wanting to know anything in general about the Commander PM me with questions. I have one on my truck and I like it fairly well.
I'm not sure about the 6.0's but the 7.3's only get boost readings to about 25 psi because that's all the higher the MAP sensor will read. Supposedly they are coming out with a sender you can install to read boost 0-100 psi but they have been saying that for 6 months. I have a seperate boost gauge installed in my truck.
