The RENNtech R3 package for the AMG GT Black Series consists of an ECU upgrade, stainless steel downpipes, BOV adapters, BMC air filters, Stage-2 turbo upgrade, and an upgraded performance clutch and TCU upgrade. Besides this, the company has also thrown in a set of Track Series forged wheels.
The stock Black Series packs a 4.0-liter twin-turbo V8 that belts out 720 hp and 590 lb-ft of torque. The RENNtech upgrade pushes the overall output to 1066 hp and 831 lb-ft! If you aren’t feeling brave enough, RENNtech also offers an ECU upgrade for $4,480, which boosts engine performance by more than 99 hp and 95 lb-ft.
The Black Series comes with a unique aero package, featuring a low front splitter and fender louvres. It also has a 2-piece rear spoiler which has an electronically adjustable flap. The tuner doesn’t seem to have made any changes to the interior.
