This is a very interesting thread. I just installed a red Magnuson supercharger but don't have a boost gauge (don't want to tear apart the top of my steering wheel or corner post). The ZL1 4 pack gauges would be sweet. As per Ted's recommendations, I put in a ZR1 3 bar map sensor with the supercharger install. I'd want the Canadian version of the gauges, but all I would need to do is switch out the gauges and plug in? I have a 2013 1LE. Would I need to get my custom tune (Ted J) tweaked to work on the GM gauges? The gauges are under $200 I believe so it would be a "cheap" way to get a boost gauge
Anyone know the part number of the ZL1 4 pack gauges?
