I was thinking maybe a lower rpm tachometer on the dashboard for the D-Series, the current dashboard has a tach that goes to 6,000 with a redline of 5,000. Since the diesel engines usually go to 3,500/4,000 rpm the tachometer should read up to 4,000 rpm with the redline at 3,000 rpm, as well as a boost gauge for turbocharged diesel engines. Here's a gauge cluster from a 2016 Ford F250 Super Duty Powerstroke for reference Make changes as needed, all I ask is for a similar layout to this with stylistic changes to match facelift and pre-facelift models of the D-Series
