Overview
Mercedes AMG’s hot inside V turbo V8 is a high value software platform because the engine has strong factory hardware and a conservative torque model from stock. The MED17 strategy gives tuners excellent authority over boost, ignition and torque request, so even Stage 1 produces a very large real world gain. With downpipes and cooling support, Stage 2 keeps exhaust backpressure under control and helps the engine pull much harder past the midrange.
Key Features
- Halo four door AMG
- massive gains
- top tier market
