As long as you "can pay to play" (tuning will void your engine and drive train warranty) a well R&D tuning can be had from Renntech (US company) and Rebellion Automotive (UK). Rebellion notes a 78 ft lbs increase in toque and a 44 hp increase; Rennteck numbers increases to 428 hp and 417 lbs torque. With a performance down pipe you will see a bit more increase in both hp and torque. The AMG exhaust and CAI are excellent to start with and really need no upgrading.
Price wise Renntech is $1780 and Rebellion is (at present rates of exchange) $910.
