RVs on dragstrip
Among the gas engines tested, the Ford F-150 with the 3.5-liter EcoBoost engine showed the most improvements with the 5-Star Tuning programming. Towing a toy hauler on the strip, the F-150’s time was cut from 13.64 to 11.85 seconds, and speed went from 51.49 to 59.11 mph.
The F-350 diesel test truck was strapped down and hooked up to 5-Star Tuning’s Dynocom chassis dynamometer. Electric fans were placed in front to facilitate engine cooling. The building is large enough for a truck and trailer to drive through.
