engine performance upgrade for 320 CDI

I was looking at the website fo Kleemann. They have this engine performance upgrade for the 320 CDI for the ML. I guess it is the same as the engine for the GL. Anyway they call it KD BOX which they claim to increase the HP and torque about 25%. Has anyone have experience with this KD BOX? I know that Kleemann has a good reputation with regards to engine upgrades but they are a little bit pricey. They don't even list the price I guess you have to go to a Kleemann dealer. It looks on the picture as plug-n-play and no need to open the ECU. looks like a piggyback connection.

Sounds like something that might negatively impact gas mileage which helps defeat the purpose of buying a 320 in the first place.

Kleemann claims 25% more power and 5-8% better mileage. This is consistent with people I know that have chipped their diesel engines in pickups. The question is, how much you enjoy the extra power and if you can keep your foot out of it.
