It almost seems like an insult to take a supercar like the SLS AMG and hand it over to a tuner for improvement. With more than 500 horsepower and a competition pedigree that’s being reinforced by the number of privateers entering the car in the FIA’s GT3 class, the SLS AMG doesn’t seem like a candidate for improvement.
Inden Design, however, has seen fit to tweak the SLS AMG just that little bit more. Starting with the engine, Inden has bumped output from 570 horsepower to 623. The 50 horsepower bump was achieved by replacing the exhaust with freer flowing bits and remapping the ECU. To better handle the increased performance, the tuner also installed 10.5X20 custom wheels shod with 265/295 tires front and rear.
