E63 / E64 6 Series (2004 - 2010)
The E63/E64 BMW 6 Series builds on BMW's sporty heritage with aggressive lines and an incredible motor to back the design up. Available in coupe and convertible trims with a standard 4.8 liter engine producing 360 horsepower and 360 lb-ft of torque, the 6-series is a popular choice that exceeds expectations.

hesitation/RPM drop

I have a weird problem. I can fee, and see on the TAC about a 500RPM drop during moderate to hard acceleration in gears 3-6 somewhere between 2500-4000rpm. There is no special sound like a ping or a miss, the engine just drops in rpm and then catches again. My PEAKE meter sees no codes. Could it be a condenser? Can I isolate it to one or should I replace them all? I have about 50K miles now.

You may want to post this in the main 6er area. The DIY forum gets much less traffic.
