and that little pulley determines whether the car is sluggish or not, or is that affecting the rough noise

those numbers are way too high for a stock engine. Yes I would like to see the dyno sheet as well. even a 330 doesn't pull that

i don't disagree at all, well a 330 is up to 235hp, a 328 is 190hp, i know that a stock 323i is 170hp,

How long has it been sense you (or someone else) changed the spark plugs?
How long has it been sense you replaced the air filter?
We will start with the simple things first.

Has this lack of hp been going on for a while? Has it been a gradual change or something within the last weeks or months?
I am hoping to keep this thread going so we can get more help. My general automotive knowledge is fairly good. My BWM specific knowledge is not that good.
You are not going to get a gread deal of hp out of a 323.
