Well done to Justin Mather for winning the 2015 P3 class in the final race of the Porsche Club Motorsport Speed Championship at Prescott Hill Climb. This was the last race of the season and put Justin first overall in the P3 class and a close second in the championship. Justins car was running an AugTronic ECU with 2.7 Litre engine fitted with our race cam. Check out Justin’s video of his best run of the day:
