OK, just talked to the tuners, here´s the scoop on the C63 AMG. No way you can get 65 additional bhp’s from the chip. They literally said that is “waaaay to high”, they are getting about 20bhp and they can do that for $1,495. They are currently producing headers as well with 200 cell metal cats that are $4,200.00 (5 hours labor to install these) and they believe they may get perhaps 50bhp total (ECU + headers) with all this. If anyone says they can get 65 from the chip alone, they are lying!!! The SL63 makes 518bhp SAE (525bhp DIN) due to improved headers, downpipes and exhaust as well as a slightly improved intake. The CLK Black Series is around 500bhp (I've seen 500bhp figures, probably SAE as well as 507bhp figures probably DIN).
