Dynojet’s Power Vision is said to be the quickest and most powerful flash tuner on the market. It works without the use of a computer in that the interface cable plugs directly into the bike’s diagnostic connector, and users can follow on-screen prompts after selecting a tune. Dynojet preconfigured tunes are preloaded onto the unit for all Harley-Davidson models with the Delphi ECM (except 2011 Softails), the company says. One can also load custom tunes onto the Power Vision.
