• A look at Weistec's M133 (CLA45/GLA45) upgrades - ECU tune +126 wtq, W.4 Turbo upgrade ~500 awhp

      The CLA & GLA 45 is often overlooked by performance enthusiasts and is not generally regarded as a high-power platform, but we at Weistec disagree. We have worked hard to provide the BEST tune on the market for the M133 platform, not only in numbers but also in sheer power delivery. Our tune sees peak boost and torque at 3000rpm, getting off the line with 428awtq and carrying through to the finish line using 356awhp-- With nothing but our tune!

      M133 ECU Upgrades

      Bang for the buck, this is your best option for quick and easy power.

      AMG's M133 platform is definitely a performer, and has a ton of available potential as what would be expected from a Mercedes AMG vehicle. We offer a complete line up of parts and accessories for this platform to make sure you get every ounce of power available and would love to be included on your next build.
