So Im buying an autometer boost and EGT gauge and an AEM Wideband and I wanted to know how big the difference was between electric and mechanical. In willing to buy the full sweep electric but if a mechanical would work just as good, Id like to save the money. Also wonce I buy the gauges is there anything else I need to buy in order to install them and for them to work? Are there any wires or anything I need to purchase to get the gauges to work? I already have the pod. Thanks for the help.
