I am wanting to get a boost gauge and was wondering the pros and cons of the different gauges, mechanical versus electrical. I have heard stories about both. The mechanical is not good because of the air line possibly getting pinched versus the electrical bad because there is more that can go wrong with it. I am looking at the Prosport gauges along with the subie gal single pod. Let me know your thoughts. Dont want to spend an arm and a leg because then it would make driving the car harder.
