For the last 4000km my mini works with a 15% pulley, new plugs and a K N filter panel
the car goes realy good and you get to rev limiter quicker than before but even the car pulls from lower revs there is lack of torque between 800 and 1800 revs or so .
I think thats the case with most stock
MCS too but i think after the upgrade its doing it more or its more obvious.
Is that normal? have i to do something? has anyone noticed that?
