Performance upgrade E63

[nlaw]

Hi. I'd be grateful for any advice if possible. I'm thinking of getting an upgrade for my 06 E63 AMG estate and wondered if anyone had any experience or advice as to who to approach or indeed if it's possible. I spoke to an AMG mechanic as well as Brabus who stated that modifications weren't possible. However, I did receive a quote from Kleemann for an ECU upgrade/supercharger.

Cheers

cheers, site's down at the moment (MSL that is), but looking at Weistec it seems they cater for the '07 engine and up
