hey everyone! well, i finally got the YRF0 tsb done to my car.. but for some reason, it still feels the same? i have an '03 2-door, and i know the YRF0 changes a lot of things, one of the most noteable, i guess, is the DSI swith from 6k to 5k. after i got my car back from the shop, i took it out to the highway to see/feel/hear the difference.. sometimes, it would switch at 5, other times at 6.. is this normal???
