Boosted Tuning for BMW's
I am a new owner to bmw, and my e36 325i, I am just wanting to know from the people that are boosted, what means of tuning they are using?
What is the most commonly used/easiest means of tuning used in bmw's?
My long term goal for my car is 350-400rwhp, but I won't be able to even think about this for a year or two so in that time I want to research and learn as much as I can.
Thanks ahead of time for any info that you all can share
