Well im new to this all this remap malarky having only owned N/A vw's in the past, and I have just purchased a mk5 gti and I've decided to have it remapped, my question is would my car still retain it's current mpg when just plodding around? i know when on WOT its going to be worse but as I do quite a bit on the m'way id like to retain the MPG I am currently getting. thanks for any help!
