that's an impresive powerboost!!! from 367 ps of the NA 5.5 to this!! hope they've done a great job with the chassis and springs!!!
and I 'm sure there isn't a lot of differences between this version of the 6.3 and the cls one.....must be electronic or exhaust......so the power must be easy recoverable...
I'm curious what the mb tuners 'll do with this masterpiece of engine...!
