I purchased the tune at the Miami Eurocharged Tune/ Dyno Day and loved the results. Put down almost 350whp and the gains were obvious.

3 days ago I took the car to a MB deal for maintenance work and the mid-range power seems to be gone. Unfortunately there is no way to know if the tune was actually wiped off when they reset the odometer.

Has anyone heard of or experienced a tune being wiped out? Maybe its all in my head?
