I Had my Audi a4 tdi 130 remapped (not evo soft ware i might add) but by anouther fairly weld known tunner an although there is a definate increase in the power department i can honestly say the mpg hasnt improved, if anything i reckon its a little worse than before ... Now i know your all going to say that must be down to the way i drive it but honestly these days apart from the odd bit of a blast i normaly poodle about watching my fuel consumption lol...
