This is probably the best piece of information I didn't think about. If I'm guessing correctly the w204 c63's are 2.82 gear ratio, and the 392's are 3.09. Not much of a difference but still something.

Add to the mix LTH's and E85 for the M156, and some other minor bolt-ons and 520rwhp is doable .... while the SLS stuff makes amazing HP it does cost a ton and drops torque on the lower end, and then there's the cost....
