Got I bit of problem with my "new" MXU 400 IRS. It starts fine, runs fine until you try to get all out of it. It accelerates pretty easily to 60km/h but after that it is painfully slow. It wont go over 70km/h at all. Ive read that its supposed to get over 80km/h max speed delimited. What should I check first? Also gasoline consumption is awful. It took half tank in 30km trip with no leaks.
