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.

I would be very interested in what you find concerning price and to see
if does fit the GL....Also where does this plug in at???

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.

Wait until your warranty is expired.

Or, assume it will expire on installation.
