I'm just wondering if I should get a 2 or 3 gauge pillar for my truck. I've already got an autometer boost and pyrometer gauge, but was wondering if there was anything else you guys would recommend monitoring, or if the stock gauges are good enough. Only thing I can think of would be tranny temp gauge, but I've heard the stock one isn't that far off. Also where can I get a full dual or tripple gauge pillar for the cheapest?
