A little dissapointed with the mpg on my 1.8t 190 bhp b6, and feel there are some flat spots on the acceleration at certain points. There have been some issues with the car lately but all being sorted, however when all is done i am thinking of having it remapped. A friend of mine has just had his VW golf gti 1.8t remapped with a rolling road test and says it feels a hell of a lot better. So i ask you all as you are all so much better informed than me the nube, is remapping the 190bhp 1.8t a good idea, does it have to involve a rolling road, what really have been your gains if you have had it done??? You views and advice please. cheers Vince.
