MB CL600, Audi RS6 and Porsche Cayenne S
For all who are interested I have confirmed that the $699 price applies for the W215 V12 biturbo. I know a few years back the price was $499, but unfortunately I didn't own a CL600 then. I am also told they will include the TCU for $200 more which leads me to my question:
Is the TCU necessary? It's a permanent mod and I'd like feedback on the improvements with the TCU as opposed to just the ECU upgrade. Does it make the shifting faster, or both faster and harder. I feel the car shifts pretty well and if the improvement isn't substantial I'd rather just do the ECU. Are there any drawbacks?
I know some of this has been addressed but not recently and not definitively. Thanks.
One more relevant piece of info: My vehicle is still under warranty for another 50K

Our TCU tune modifies torque management settings, reduces slippage, and shifts faster as well.
Please let me know if you have any other questions or concerns
