I bought a 2006 CLS 55 AMG with 70k miles on it. The car looks and runs better than I hoped for when searching this particular model out.

The car has an under pulley and a custom x-pipe exhaust, magnaflow. the owner did not have it dyno tested however he said the exhaust should give up to 30hp and the pully another 10-15hp. If in fact this is the case I am stock 561 ft lb torque at 2850 rpm and close to if not a little over 500hp.

My question is can anyone give me feedback on chip tune? is the hp increase of any amount under 50hp worth the investment? I only use the number 50hp because I am not too sure i'd notice a gain under 50hp.

Anyone have any other suggestions on how to increase the hp?

thanks!
