Development package c63
So, yes.....I reckon the Development Package is well worth while....I mean, it's not just a "tune" is it.....SLS crank, rods & pistons, give the engine, and the car, more "individuality" & "character"....IMHO.

I'll throw a minor wrench in there - if you're not concerned at all about warranty issues, then I wouldnt go P31 and instead would put that money towards ecu/pipes which will be result in way more bang for your buck. Me personally, I dont want to deal with caselaw and "the mod didnt cause the issue" blah blah blah arguments with the dealer, so no go on mods for me.
