German tuner McChip has revised its tuning program for the Mercedes-Benz SLS AMG. In its standard configuration, the V8 6.2-liter naturally-aspirated
engine produces 571 HP (420 kW) and 650 Nm (479 lb-ft) of torque, but
the tuner can increase its output to 706 HP (519 kW) and 793 Nm (585
lb-ft). They do this by installing a custom exhaust system, sports
catalytic converters and performing engine software tweaks. The entire
power upgrade package will set you back 78,999 EUR.
Aside from the power boost, a hydraulically-controlled DDC or HLS
4-sports chassis made by KW is available for 12,999 EUR. CoverEFX is
selling this complete matte grey/red foliation for an extra 5,999 EUR.
Lesser upgrades are also available, while the most powerful version
is for export only. McChip says the modifications are made in 5 to 7
working days.
