We know how well the VR Tuned Tuning Box kit works on the Mercedes CLA250, now we have had a customer install it on his GLA250.  Same engine, same performance, different look.  The plug and play tuning box gives the car an additional 42hp while taking only 5 minutes to install.  Increasing boost and adjusting the fueling and timing, the Tuning Box delivers better torque and throttle response.  Very warranty safe since it can be removed, the GLA 250 ECU Tuning Box is a perfect stage 1 upgrade!  Check out our customers pics below.
