Just curious. And how many others are planning on doing some tuning in the future.

I'm waiting for all the factory updates to take place before having mine tuned. I would think by the first year, all the updates should be completed.

Also, as more and more owners of C63's and GTS's have their cars tuned, I'm hoping that the price will drop some. I was offered a tune for $ 1995. which I thought was fair, but, the price increased to $2495 same tuner a few weeks later.

I may tune mine as how my Renntech wagon is currently quicker but have not decided which tuner I might use for the GTS yet.

I have mine tuned by Weistec and have also done catless downpipes and midpipe. The car is a beast and really wakes it up.
