exactly.

my car ran greys, 2.5% c/o, a LOT smoother than when on std injectors (temporarily on std inj chip on few occasions and felt horrible), and unless your giving it loads, not noticably worse on fuel, if anything it better as didnt have to use so much revs/throttle to get anywhere.

and a live map by stu etc id be sure would be even better than that.

and like stu said, may as well go to 750s
