I know a growing number of you have BMW's and I have a question.
Is there a local "Hermann" or "Jon Lund" of the BMW world around here?
I ask because a friend of mine has 2 M5's and he thinks one is down on power but the BMW mechanics he takes it to say everything is fine. He is a pretty experienced OT driver so knows cars pretty well and just cant figure out what is going on. He is trying both the cheap dynolicous Iphone App and a G-Tech unit but wants to really determine if it is all in his head or if there is truly a problem.
I suggested a more quantitative method might be a simply dyno test for both cars so he scheduled some runs this week at a local dyno. But even then he wouldnt have these guys mess with his tuning, it would be just data collecting and perhaps a starting point for him.
I know both Jon and Hermann when tuning will be happy to work with you, explain things etc. Is there an equivalent of those guys around the DC area in the BMW world?
Thanks
