Did you know....
I've found something interesting last weekend, and I know I should've shared this info with all the ML63 owners out there, but I don't want to be held responsible for damages. 
Anyway, did you know that US bound ML63's have carbon filters sitting in the airboxes? Reason being is to reduce emission, but that also robs power. I know BMW's have that, my old E60 530xi had it, my M6 has it, but I've never thought MB would use that in its AMG vehicles.
So anyway, I removed them, drove around without them for the past week, no check engine light, and my truck does seem to respond better. 
Here's what you do, remove the 2 boxes from the car, open up the air boxes, remove the carbon filters (they are the grey filters) which you simply slide them off, put everything back together, and enjoy your trucks.
Hope everyone finds this useful.
I don't know if other 63 vehicles have them, but if any E, CLS, S, CL, or CLK owner reads this, it wouldn't hurt to open up yours to find out.

Yes, I removed the secondary carbon filters (for emissions like you said) from my M5 and noticed the car pulled stronger down low. It's a popular mod among the US M5/M6 V10 crowd and I believe someone actually dyno'd it before and after removal and there was a solid quantifiable gain. I'd expect similar results on the ML63 though I don't know if I'd bother.

How can they be US bound if they are made here...are any ML's made else where

I think he was referring to cars that were produced for the U.S. market
