  1. A definite improvement 4 Star Review

    Posted by on Aug 30th 2016

    After a bit of a rough start, having not been able to get the "green light", I static timed the motor, fired it up and then set the curves. Mileage has improved, the engine runs cooler, and the app is pretty good so far. I'm looking forward to seeing how this imporves.
