Those familiar with the Mercedes SLS AMG know all about its raw performance and stunning beauty. So it’s not necessarily the first car we think of in terms of receiving an engine upgrade. But low and behold, German tuner McCHip-DKR put their touch on the super-sports car—equipping it with a Stage 1 power boost that increases output of the 6.3-liter V8 from 583hp to 654hp. Torque looks to remain at 479 lb-ft. The remapped ECU provides extra horsepower. Ballers looking to add it to their collection can pick up the package for 3,199 Euros.
