PTG M139 Performance ECU Mercedes-AMG Tune
The engineers at Premier Tuning Group have been hard at work with the latest M139 AMG engine. This engine shares many philosophies of the older generation M133 however it brings forward several new design features that make this engine one of the best kept secrets in performance.
The M139 engine is very unique in the AMG family mainly because it is the basis platform for the upcoming C63, but also the fact that it includes eight fuel injectors from the factory. Yes, eight. Similar to other manufacturers, AMG has now included port injection as well as direct injection, allowing us to properly time and tune fueling for the first time ever on an AMG.
The power outputs even stock were quite staggering however when tuned, this engine and absolutely amazing.
