The temperature gauges are non-adjustable BUT you can check to see if the gauge or the sensor or the wiring is the problem. Tom changed out his gauge to a digital gauge. The probes were reading 25 degrees high. He changed to a twin sensor lead and the gauge was within a couple of degrees of a candy thermometer and an infrared temperature gauge. Grounds are extremely important in the readings on your dash gauges. I will have to redo my grounds as my gauges have gotten more inaccurate with time. I use the VMSpc software on my laptop when I am driving. It gives me the readings directly off the DDEC computer. Tom has the same software and we read within a degree of each other driving down the road behind one another.
Both Richard and I have IRSI air seats in our coaches. They are VERY firm. Richard took the upholstery off my seat, as he had with his, and added a couple of layers of memory foam over the existing foam then put the uphostery back on. It is held on with clips on the bottom edge. My air seat had been disabled by the previous owner due to air leaks. We replaced the air line under the seat, replaced all the plastick fittings with metal fittings and readjusted the air valve control. Works well now. After I have driven a few hundred miles, I may need to increase the lower ride height as it seems it may bottom out but I am thrilled with what Richard did for me. He is truely a master.
