Dear Sedox Performance,
Thank You! Thank You again! After visiting several of garage tuners and trying to get my M3 faster, I finally came to the right spot! If only I visited You sooner...and avoid all the problems with car not starting and all the control lights going on...
Finally the car is tuned with a proper software and the car goes great! The power is low RPMs is just so much better then original...and the V-max is almost 330 km/h on the clock! :)
