I am looking for real information on the 2012 ML63 AMG Performance Package.

I read that they changed the color of caliper, put in different steering wheel, and upped the boost pressure. Are there any other "physical part changes" or just "electronic changes". What I am fishing for is did they put bigger fuel system, bigger injectors, different suspension, etc. Or in simple terms, did they just reflash it with a hotter/higher boost profile which similar could be done by a reputable tuner.


Thanks in Advance

Boost pressure is raised from 14.5 to 18.9 psi. The only physical changes mentioned thus far are cosmetic: Dinamica with leather on the steering wheel, AMG engine cover in high-quality real carbon and the red-painted calipers. Fuel economoy does not change (unless your foot is in it). 0-60 drops 0.1 and The top speed is raised to 174.

Greg,

Thanks for your response. I ask because I need to finalize the build configuration on one that will be built middle of March. Dealer doesn't have much "real" information. If it's cosmetic with a factory re-flash it makes it real hard to justify the additional cost of the AMG Performance Package. **IF** the Performance Package adds upgraded fuel, injectors, etc that would extend the tuneability further than without the package, then it makes real good sense to purchase it.

Thanks

We just don't know the extent of changes related to the higher boost pressure. More fuel will be required at the maximum, but we don't know if the stock system was designed for it or if other parts are upgraded. Maybe more info will be forthcoming.

Hi does anyone now have some verified info on this? 8 years later so hopefully! Nothing on the net I can see...
