Out of the bunch of BMW tuners, some are world-wide known for their incredible performances and power gains with little to no effort.
One of them is, of course, AC Schnitzer. They have a program for every BMW model out there and no engine was overlooked, the complete line-up offering up to 93 more HP with some minor tweaks and tricks that use plug-and-play technology.
However, the ACS programs are not something new. We knew about them ever since they were released. The German company though, decided to change its priorities and emphasize the efficiency of their programs.
You might say that's madness and that no extra power can be gained without increasing the CO2 emissions. Well, according to them, it is possible. Most of the 80 programs for BMWs make sure that even though your power levels increase, the fuel consumption and emission levels stay the same.
