So I have 2 2014 GTI 130 SEs and I've always been able to get 54/55 mph out of them flat out. I was out this past weekend and my buddy was on one of them and couldn't get past 45. I had him start next to me and we both pulled the throttle down all the way at the same time and within 10 seconds I was a good 50 ft ahead. (He said he was hitting 45 and mine read 54) He then put it in sport mode and matched my speed of 54 remaining next to me the entire time. I know sport mode only messed with the aggressiveness of the cornering and increases acceleration so I'm confused as to what would cause this. I haven't gotten on it myself so there is potential it's operator error but I do not believe this is the case. Next time I take them out I will hop on it and look at RPM's and everything but I just wanted some preliminary advice. Anything advice is appreciated. I will be bringing it in to the shop if I find the same issues next time but just wanted some information to go off of.
