Dennis’s Mercedes-Benz SL55 AMG in for an AMR Performance ECU Software Upgrade (tune). Base line dyno pulls show the vehicle putting out 358hp and 430tq. This vehicle was very well maintained and the base line dynamometer numbers (dyno) show it!
Our engineers went right to work. The ECU Software was reprogramming with our AMR Performance Stage 1 ECU Software upgrade (tune) which immediately gave the vehicle an increase in throttle response, firmer transmission shift patterns and removed all of the vehicle’s delay throttle and hesitations throughout the power band.
Final numbers on the AMR Performance ECU Software upgrade showed 420hp and 485tq giving a gain of +62hp & +55tq with only our tune making the vehicle very stout and potent on the street!
