A pillar mounts
I drive some hilly and curvy roads and sometimes find myself having to crane my neck to see around the A-pillar, without the guages. Regardless, I plan on installing two gauges on the A-pillar, the combo egt/boost and a fuel preasure. From what I can tell after holding up the dual pillar mount with the gauges, I don't think it will be any worse, but even if it was, I would rather have my gauges at eye level so I can keep my head up. The way I drive, the curves come up real quick and I can't afford to be looking down to monitor the gauges. IMO, the benefits of a a headsup gauge mount outweigh the downside of "possibly" creating a slightly larger blind spot. Looks cool too!
