I have a full set (boost, egt, oil temp, oil pressure) of the smaller prosport gauges. Just so you know, you don't have to run the gauges amber.. they can be amber, red, or white. The red is an amazingly perfect match for the stock MS6 gauges.
I haven't actually gotten to use my gauges yet, but they are hooked up. I can let you know how they actually perform in a few days when my car is back on the road.. as you can see from my signature picture she's very apart right now.
