wow, congrats!! that's pretty exciting gains. I'm definitely looking into it for the wifes e90 now.
On a side not I can't stress enough how much I love NA inline sixes from BMW. I've been driving my new x5 w/ the n55, albeit different cars, my wifes n52 is so much more exciting and engaging. Just solidifies my decision to go n52 over the n54 on the e90
