I sent my ECU to Kleemann..
Feel a little nervious because I didn't pay extra for package insurance but anyway the ECU is heading to Cory via Fedex. Hope to notice some gains after Kleemann tuning...

Did you remove the ECU yourself?
Why skip out on 15 - 20 bucks insurance on a 1500 dollar item.
Either way, enjoy it.

You'll feel the gains - AMG left a lot on the table with the C63. I'm sure I don't need to tell you this, but: HAVE FUN OUT THERE!!

Yes, I got the ECU back from Kleeman today and put it back in...WOW!! I haven't even pushed it really hard yet but I can definitely feel more power. It was totally worth the $1500. All I can say is that the difference is noticeable. I had it dyno'ed prior to doing this and feel no need to dyno it again.
I now have access to the true power for which this engine was built. Very happy.

Curious though, why not dyno again to see exactly how much rwhp/rwtq you picked up? Is it the cost and/or hassle of visiting the dyno shop?

As for shifting lag, I have not noticed a change but haven't really paid attention to it yet. What I have noticed is that there is no lack of power when I accelerate as I sometimes felt when in sport mode until it downshifted. It seems the TQ band is wider.

I had a very noticable hesitation when slamming the gas from a 40 or 50 mph roll. Almost felt like the car was taking a deep breath before taking off.
After the Kleemann package it just nails it as soon as you press down on the gas and does not let up till you do. I honestly can't tell any difference in upshifts but the tranny shifts lightening quick already.
