Question SLK Newb needs help

I am a newb to SLK's and this site. I joined after reading some of the great posts that people leave here about how to make repairs to their cars. My issue is on a 2003 slk32 AMG. The car was beginning to lose a lot of power. Tune-up did improve slightly but the big issue remained. When car starts it has lots of power. First time you hit pedal it takes off fast. Soon after you can stomp on it and it moves like a Ford Focus. It seems to be the worst when it is warm outside. I was certain it was the fuel pump but the pressure seems to hold steady in the recommended pressure range. No codes show up at all. The horsepower is lacking when you take off from stop and at 60mph. Any help is greatly appreciated!!

Could be alot of things, dirty injectors, dirty fuel filter, dirty MAF, S/C not working. Hard to tell without codes or seeing the car.
