No you will need gauges. The programmer plugs in to the port under the dash and can either change the programming (power level), measure performance, and pull/reset trouble codes.

The Evo programmer is a rectangular gray box that looks like an overgrown Game Boy with red buttons and a blue digital screen and a cord coming out of the top.
