When using my shift paddles on my 2006 CLS55 I find that the shifts are pretty slow and mushy. Almost like the old Chevy power glide transmission. Certainly would never be able to squeak the rear wheels even while leaving it floored.

Is there any way to speed that shift up by reprogramming the ECU?

Thanks Popeye

A TCU tune will help a little bit. It will firm up the shifts, remove some torque limiters and decrease the lag between gears. Just don't expect anything remotely close to an old school "shift kit".

You need a TCU tune

I agree a tcu tune is in order.
