Yeah I know, it's not only Power Chip but SI is doing this also.. it's all the same programming for the SLK320, yet it is cheaper because it's out of production, supply and demand guys, they are mearly just capitolizing off of the demand for more power. Though I find the price of $400 to be way out of line for only 20hp. I'd rather put that $400-$600 towards a supercharger kit when ever that comes out or towards bigger brakes.

why don't you just tell them this is for the slk320 and not the crossfire
