I found the chip didn't help untill i replaced various sensors, so unless your up on maintance i wouldn't bother.
best mod for the buck is a bavauto short shift kit, some weight reduction (ie. carbon or fiberglass hood), some ultra lightweight rims, tweak the cam timeing (cams are adjustable)
I found this site to be very helpfull
