I want to add a boost gauge to my 2007 Mustang GT with the Edelbrock Supercharger kit. I am leaning towards the AutoMeter / Ford Performance 3 gauge center dash cluster: I think I want to go with the Ford Performance Gauges that Autometer makes: Boost Gauge is a FOR SURE - damn that thing is expensive! The question here is what other 2 should I get? I was thinking, the Water Temperature Gauge - well cause these cars can get hot. Maybe the Transmission Temperature Gauge? I have no idea how that hooks up never installed one. So the car is a GT Premium so it has the 4 center small gauges from the factory: Fuel Temp C to H Voltage L to H Oil L to H So not the most useful in the world except to tell me if its well already too late or I need Fuel. So please make suggestion and tell me anything you have to add.
