RENNtech is pleased to announce that after long term testing our stage 2 performance upgrades are ready for the M133 engine. Making 455 HP and 555 NM our stage 2 kit is the ultimate upgrade for Mercedes newest two liter turbocharged rocket.
Since August, RENNtech and RENNtech Engineering in Germany have been pushing the tuning envelope and have made significant gains in performance including turbo upgrades and the ability to remap the ECU. Months of real world Autobahn testing of our M133 stage 2 kit has resulted in full TUV Certification.
In addition to our stage 2 upgrade we currently offer a performance downpipe featuring a high flow, specially coated 200 cell catalytic converter. This converts exhaust gases better than anything on the market and unlike other downpipes will not set a check engine light during long term, high speed driving, even on US spec cars.
Future developments for the M133 include additional exhaust components and a unique carbon turbo heat shield. Our heat shield is crafted from the latest CMC carbon material which exhibits extremely low density, excellent thermal insulating properties and low thermal conductivity. This is a real upgrade and insulates the turbo charger rather than a stainless shield or similar material that actually conducts heat into the engine compartment.
