Hey, nice choice!
Why don't you buy z4 35i and save on "s" and get JB4 + exhaust + intake (and still save some cash) You will get better performance than z4 35is for a better price.
For chip tunning there's no difference if you have "i" or "is" it gives you equal output. And I would choose JB4 over any other mod.
