The only viable option I see for boosting the NA motor is to buy an SRT6 ecu and get it reprogramed and the vin unlocked. wire that into your car, there are a couple tuning maps available from Bosch for the AMG and srt6 powered cars.
otherwise you will have to wire in a stand alone ecu, there is one company in Westminister who has success tuning a Mercedes SLK320 r170 chassis car. I already posted thier number and website. good luck.
