Why doesn't the Mercedes Canada website say anything about Performance plus engine HP increase?? I can't figure out if its all the upgrades minus the engine increase?

Also, whats the word on tuning the 487HP engines? Are they getting even more power when tuned? Or is it basically the same as previous 451hp engines?

Probably a little more since it seems like they reduced some of the weight? I doubt it would be much different from an 09 with a tune.
