Well, you just have to open the hood and look at the throttle body to confirm it. No throttle cable, no cruise control cable, plus the drive by wire TB looks different, instead of TPS, IAC, (each with their own connector), throttle lever, vacuum take-offs on it, there is just a big plastic body with a big triangular shaped box on the side of it, with a single big electrical connector to it.
The Commander only came with Automatics, I don't think a "sprint booster" would be necessary. As well, you can argue its better on the automatic trans to operate the throttle smoother with DBW than a direct cable where some people just mash the pedal.
Although I'd be interested in hearing the results if someone wanted to try a "sprint booster" on a Commander.
