SPEEDDRIVEN BLOCK TUNER
Has anyone use a Block Tuner from SPEEDDRIVEN? I am interested in the ability to swap from the original tune to a valet type tune that will limit the RPM and MPH of my C63. I am going overseas and need to ship the car but do not really trust leaving the car for someone else to have fun in at my expense.
