Well, it does not feel slow, and I doubt I will be able to find a dyno here... If it is indeed not putting down the best numbers, it could be that my airfilter is full of dirt, because the air-polution is pretty significant over here and we also get dust storms and I never had it checked. Is it possible? Or it could be the poor fuel quality which varies from station to station in China. No matter, the differences between normal/stg1/stg2 are definetely there. I will try preparing some more videos and check back in with you...
