Been using glowshift gauges for awhile but my first time ordering their pillar gauge kit. Fitment on my 03 Ford 6.0 Superduty was pretty good. Typical excellent quality with the 2 gauges I chose. For my setup I picked fuel pressure and EGT. I then use a SCANGAUGE to monitor boost/tranny temp/oil temp/coolant temp. Best bang your buck. I like that they offer specific adapters for my rig. Takes the guess work out of buying these things. Also purchased the drill & tap kit which worked great.
