Lack of Performance mods/upgrades for the new E53
Is it simply because it’s so new?
I haven’t found anything from major companies like Renntech that can confidently confirm compatibility.
Even with the ASR module, I followed the instructions precisely, and yet, the CEL light came on!
Please, what are my options to restore Brunhilde’s beautiful voice?

Yes Brabus is like AMG pre merger just that Brabus is a lot larger. They even built some of the pullmans for Mercedes I think.

AMG E53 214.063; BMW IXM
The BRABUS B53-700 power kit is available for ordering. Figure about 10-12 biz days, shipped to your door in the US. Purchase price is $9,995.00 plus shipping and tax. Been in contact with them since I got my E53 and they reached out once it was available.
The BRABUS sport exhaust is not yet available, they expect only a mild decibel increase from the AMG exhaust, due to engine turbocharger application and the restrictive catalytic converters.
They also have adjustable sport springs, 15-30mm variance, available for $3395.00 plus shipping and tax.
Be advised there are warranty implications, I will have mine installed at my AMG dealer, and they said as long as they do the installation they (MBUSA) will honor all warranties

I came across this recently... power upgrade and sound upgrade by Mariani.
Anyone have experience with this company?

Valid point, for example I have a close friend that works at a MB dealership here in Canada and there are zero cases of reported turbo failures with the M256. The dealership is a volume dealership, so I couldn't believe it myself when I read the other forum member's post.
