Taking my X5 to Motor Works West | Independent BMW-Exclusive Specialist ...Heard good reviews about them and the bug to do some mod on the car...

My 3.0i struggles with the ramps on saw mill and i wish i had purchased a V8....so wondering if a 299$ minor software upgrade would add any improvement in the performance???

Though seriously tempted to spend 3 grand to get the whole suite and a Badge..
