WIN A RENNTECH TUNED GT55 AMG for $50! MBCA’s Spring 2026 raffle is at full throttle, selling raffle tickets to win a RENtech-tuned Mercedes-AMG GT 55.
Founded in 1989, RENNtech has spent 35+ years pushing Mercedes-AMG performance beyond factory limits. This GT 55 is tuned to an OEM+ level of quality with RENNtech’s RPM ECU tune, the 4.OL BiTurbo V8 M177 engine gains +90HP and +82 LB-FT through modified ignition timing, optimized throttle mapping, and precision-dialed air-to-fuel ratios. The dyno doesn’t lie - 489HP becomes 579HP, and 582 LB-FT climbs to
664 LB-FT at the crank. RENNtech’s Exhaust Valve Module opens up your factory exhaust system’s valves to 100% open 100% of the time. More torque. Earlier delivery. Stronger pull.
One car. One winner. No MBCA membership required. Your $50 ticket could put you in the driver’s seat of one of the most legendary tuned AMGs on the road. Grab your ticket now at mbca.chance2win.org. Open to U.S. citizens 18 and older where valid. Tickets are available for a limited time.
