Had mine fixed under warranty, four hours labor at dealer rate of $100. 00 an hour. Minus the two gouges in the dash board. They are not mechanics but butchers here in New Jersey.
I do not understand the issue with gauges. I had the dealer do the install.
are not pulling a Trailer but does allow the monitoring. As to the Boost gauge when used in conjunction with the pyrometer you can get a better handle on what the various DTC codes are telling you and report them to the Service Manager. I have never had a problem in this regard with the Service Manager. I have all my work done at the Dealership and in turn they ensure my truck is on the road for business every day.
