So it is custom tuned and it was done for a pulley that was taken off before you aquired the car and by chance you put on a pulley that suited the tune.

I guess that is possible.
The ECU has been locked so that nobody can change the tune.

I doubt this.
In all my time on this forum I have never heard about this so you can see why I am questioning it.

I guess I am not to old to learn.
