C350 ECU upgrade

I am in the final stages of choosing my new car, so I'm hopefully a couple of weeks away from purchasing my new C350. I did some inquiries and Kleemann just returned an email and apparently, they have an ECU upgrade for the 350 engine. it costs a little over $1100 ($1095 + $55 shipping) and it is supposed to do several things.

20 to 25 more HP
About the same level in additional torque
removes the limiter
And improved throttle response.

Just thought I would put it out there for those interested.

I am planning on doing it, but don't know exact time frame. I'll post my thoughts afterwards just in case you are interested.

I'm interested to see what comes of it. I just saw the tune on the website (I assume it's the M276) and was thinking about getting it.

Please keep us updated. I've heard of some manufacturers providing a warranty. Do you know if Kleemann offers one?

But what are the downsides? There's always a trade-off.
