I ordered it for my car along with the extra $2K for the limited slip--I'm sure most came that way.
The reason I liked the package is obviously the upgraded hp and I personally like the brakes a lot.
To me it's worth a little extra to get essentially a factory tune and have no warranty issues if something goes boom!
I would guess that everyone who plunked down the signifgant amount of cash of the P31 and Limited slip thinks it's worth it because $8K is not an option you check ***** nilly

for me its not worth it at all, as for the diff you can get a much better one like Quafie for $1100, power just do a software and get more power $1500 and suspension put on some kw's that will blow the p31 away $2000. Half the money 3x the results.P31 Not worth it..... but thats just me

$2000 is the installed price for the rear diff.
$1500 for the ECU (unless you go MHP than its $2500)
$3500 \ Faster but warranty problems if they can prove a case.
$4500 /
$2000 > Factory installed. Slower but no warranty problems. Breaks are also better. Seems worth it to me.

all parts are the same.just ecu tune is diffrent. i looked into this for months prior to my order.... I do however agree if you dont want to take a chance on warranty issues this is a way to go. the brakes are also the same ( i think in red ) but comes with better pads...

I will call a diffrent dealer to see if they have other part numbers listed and keep you posted as to my findings....

There is no reason to call the dealership. The AMG site clearly states:
AMG P31 Development Package includes:
- Lighweight AMG forged pistons
- Lightweight connecting rods
- Revised crankshaft
- Revised ECU
- Red painted brake calipers
- .......
And just to clarify....mine and most P30 cars came with LSD standard, as well as the composite brakes and the performance suspension, depending on when it was built

Very true, the biggest difference between P30 vs P31 is that: 1, P30 (most of them) has the LSD which is NOT part of of P31; 2, P30 has the stiffer suspension which is also NOT part of P31 as it has been discontinued. But what is gained with P31 are the official horsepower upgrade from 451 to 481 and some new engine parts.

Even if the P31 package only offered the engine parts differences, it would still be a huge savings as it is extremely expensive to add these parts afterwords.
Finally, if you add the price for the carbon parts, brakes, steering wheel, etc.... then the savings pile even higher.

As mentioned earlier, that is in incorrect. There are differences in some engine parts, which for some reason many people tend to ignore/neglect to include during the comparisons. The engine parts include lighter parts that are mainly adapted from the SLS motor, such as, forged pistons, lighter crankshaft, light-weight connecting rods, etc....

Or simply buying a car without a P31 and throwing on an ECU tune and get better results.
You know what I mean? All the things in the upgrade sound great. But what are the benefits? Higher redline possible? Maybe the engine rev's quicker.
Id like to see side by side results. 1 car with a P31 and LSD with an MHP tune. The other car without the P31, and after market LSD and an MHP tune. That will be the true test for money well spent.

I would def get the P31...a no brainer with the internals from the SLS. I can't believe this is being debated. Add on top of that a tune that is vastly understated from the factory. I witnessed a P31 on a reliable dynojet...425whp! No way could you get the equivalent aftermarket for less than 6,000.
