Which company would you use between the EVO sport, or Active Autowerke for the ECU and the pulley to gain more horsepower for the BMW M6.

I'd go with Dinan, only because it lets you keep the original warranty (with the 13% underdrive one; Dinan matrches the original warranty miles/yrs.), and many BMW dealers in the U.S. are Dinan installers.

i agree with snowball dinan is the best company besides they have 3 stages for ecu , every stage depents on your car and what mods in it .
soon i'll order the dinan pully and dinan High Flow Air Mass Meter/Intake Assemblies then the stage 3 ecu
