Renntech first to break the M157 600 wheel horsepower mark with their C218 CLS63 AMG, new M157 horsepower record
Congratulations to Renntech who simply keeps raising the bar on the M157 platform seemingly week after week. Renntech hit 602 wheel horsepower with STD correction on 93 octane pump gas. Yes, incredible. The CLS63 has a revised tune, intercooler upgrade, and a downpipe modification with 200 CEL cats. This provides 119 wheel horsepower over stock and 188 pound-feet of torque over stock. The best part? M157 tuning is just getting warmed up.
