Do a search as there has been lot's of discussion on this ! I would seek out post's by HDDP and or MMZTimelord as they are our resident racers on the forum. I believe you can run as high as 103 without changes to the programming but my understanding is 103 will not give you any more horsepower than 93 ! I could be wrong, tho ! Do a search !
