Hi guys. I am new on here and currently own a mk7 gtd. I love the car but not liking the power. I know in a normal gti it should give me 30-35 mpgs but my question please is what mpgs will the performance pack give me? Any thing less anything more let me know please. I don't drive crazy but like more power when I fancy it at times. So in a normal gti I expect 15 less mpg so would the performance pack give me even less? Help on this subject would be most appreciated guys. Cheers.
