Product Description

The R1 performance package is the perfect entry level performance upgrade for the Mercedes-Benz 190 – AMG GT-S. The R1 features our proprietary ECU tune for the new 4.0L V8 BiTurbo M178 Mercedes-AMG engine, which gains up to +65 HP and +110 LB-FT, based on power numbers measured by RENNtech.

In addition to our ECU tune, the R1 package comes with our stainless steel downpipes with 200 cell sport catalytic converters. Our downpipes are designed and manufactured at the RENNtech Headquarters in Stuart, Florida. RENNtech exhaust products are ceramic coated to reduce heat in the engine compartment as well as combat against thermal stress. With the RENNtech downpipes the C190 – AMG GT-S gains additional +10 HP and +15 LB-FT.

Also included in the R1 Performance Package for the 190 AMG GT-S, are the RENNtech Blow-Off Valve Adapters and a set of two high-flow air filters for the M178 engine.

The R1 performance package increases performance to 611 hp and 620 lb/ft without sacrificing daily driver comfort or reliability.
