Our customer Jose just finished installing his VR Tuned Tuning Box Kit for his 2014 Mercedes CLA250 and is absolutely pumped! As we have tested on our own dyno here, the kit makes 42bhp on the 2.0L Turbo FWD car. Its a plug and play system so it does not affect the warranty or require any removal of your factory DME. Jose left us this review, “Amazing product! Anyone who has a CLA250 I highly recommend this tuning box. Easy install just plug and play. When in eco mode it feels like in Sport mode and sport mode feels like a whole NEW CAR!!!!” Order your Mercedes CLA250 Tuning Box Kit here.
