shorter gearing.... Thats a hard pass lol. You're going to need quite a few modules changed for the diff gearing, but if you know the right people you'll be alright. Or just keep it in dyno mode all the time.

I know a good tuner in germany which is able to change the diff gearing ratio in the TCU ..... ;-)
I got a 3.06 final drive ratio out of an 2007-2009 SRT Chrysler 300. However, it wasn’t just a “drop-in” as once I rebuilt it myself, I had to remove again due to a “drone” which resulted from my NOT “Splitting the Case” as it should have been to ensure a perfect “tight” fit. I sent it out to local specialist and have been smiles ever since where in 4th gear it sits right at 55mph at 3k rpm (start of the power band!), 77mph at 4K rpm, and 90 mph at 5k rpm!
I decided to take a look at the SLS intake manifold.
It's not sold in one piece like ours.
There's a top cover that is not expensive, it's like $300, there's a main and lower box that is around $2000 and there are the guts that are around $3000.
The guts have a separate part number for the SLS black series and I'm not able to pull a price for that. But I wonder if the extra HP that the black series had vs the normal one, once again had to do with an even better manifold and even better cams.
It's possible that the lower box includes the throttle bodies but I'm not sure of this.
SLS has the Intake manifold, the camshaft and the dry sump.
The dry sump is worth 25-30 HP at higher RPM
The camshaft gives approximately 700 more RPM than the stock C63 camshaft
The intake is good to about 9000 RPM on this size of engine. The camshaft and intake give approximately 50 HP together over the C63.
SLS black series is rated at 600HP engine. Weistec has a package with Exhaust, Filter and Tune that makes 600rwhp or about 700 HP engine. The Black Series SLS power peaks at 7200 RPM, where the C63 power peaks around 6400 RPM.
M159Camshaft + M159 intake is about 50HP and power band extending about 700 RPM. Using the SLS cam with the C63 intake has been done before and it loses a bunch of power down below 4000 rpm and makes 5-10HP at 6500. The stock intake shuts it down, so larger cams than stock require the SLS intake.
I'm pretty sure it's not a normal question. There are probably some real road racer junkies that did put that type of cam in there for the higher rpm action. Or in some big dollar race series. I still have no evidence as of yet. The engine is very capable with the DOHC and all, the cams aren't that "large" and with the short runner SLS intake it should be able to have a powerband to 9000 RPM or thereabouts.
From my experience, beware - on prefacelift models, the hood won’t close no matter how much of inner hood structure is cut - I had to modify engine mounts to make it fit, but it’s finally there
I just need to find a tuner who can make good online tune for it, since I can’t find anyone in Poland who can make it happen… any leads? Can you give me any suggestions?

Highly recommend Vano @ V-Tech. He tunes all kinds of custom builds from superchargers, turbo, cams and fuel setups.
+1 to GAD, they're closer to you in Europe, and fully understands the environment & fuel usage that is available to you; on top of that, it's a safer bet to go with someone that has tuned multiple examples of the same setup, rather than someone that may be reputable yet has not tuned a setup like yours.
