im looking for a boost gauge for my setup and was wondering what the differences are between the electronical gauges and the vaccum and mechanical gauges? I see an obvious price difference between them, but whats the difference when you get down to the gauges themselves...?

 

Just that the electric ones use a sending unit and an electrical siginal and the mechanical ones just simply use a vac line. I believe it's personel preffence but i use a mechanical one and it works fine for me.

 

awesome thats what I was looking for. thanks!
