Someone is dreaming about power figures here
BMW's site claims 306 std. And a chip alone without colder plugs, and an intercooler will put you at more risk of det which will make your lovely new engine not live very long, especially if you run it on crap fuel.
Lets see if the tubby's on the 335i prove any more reliable than those of the 330d.
I don't give two hoots if you think you are quicker, it started as an off the cuff comment and a post to correct you incorrect claims, unless that is BMW changed the spec listed on their website just for you
I still say its a lovely car though
Now get that screen fabbed in.
