yes it will. more power = more fuel.

Some say that you can keep it pretty even as you change gears earlier due to more power lower down. But as soon as you decide to push forward all that hard work will be wasted.

I've not noticed any major change in consumption, it feels like it accelerates faster though  :driver:

I bought the blueflame 3” decat.  stage 2 map and nuespeed p-flo.  36 mpg no probs and 30mpg average when ragging it out of every junction into 4th lol……

Just do it, my mum has a standard GTI and does the same MPG as mine so no difference just more power
