German Tuner Mcchip-dkr gets the M133 2.0 liter in the 45 AMG models over 400 horsepower with a Stage I tune - Working on Stage III twin scroll turbo upgrade
More good news on the tuning prospects of the M133 AMG 2.0 liter turbocharged four-cylinder in the new 45 AMG models continues to roll in. German tuner Mcchip-dkr with just their Stage I tune was able to raise output from the quoted 360 horsepower to 410 horsepower. The dynograph below shows horsepower output at the crank. Keep in mind this is just a Stage I tune but what is impressive is that the torque gains start at 2500 rpm and continue to redline.
Not bad for a motor many figured would be at its limit straight from the factory. Additionally, Mcchip-dkr announced they are already working on a Stage III twin scroll turbocharger upgrade to take output up past 450 horsepower which they should reach easily. There are no pictures of development and it is likely a ways off but tuners already announcing turbo upgrades for this motor makes it an incredibly exciting tuning prospect.
