I'm coming from a bmw background, but have always loved mercedes tuning. I've dd'ed a w124 for the last 5years, love it to death..but it's finally time for more. I want to get it off the road and throw a 3.6 m104 from a c36 into it. Aside from really basic tuning parts, there really isn't much more off the shelf to do. So I was curious if anyone has ran ITBs on a m104, and possibly even a carbon airbox like on dtm cars. I know it will cost money, I know I won't get that much more power, but damn..do they sound neat. So any help would greatly be appreciated.
