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???

I just got mine done too. I don't really notice a thing different. Perhaps it bogs a little less but its still there. As for telling when the DSI switches over perhaps its harder to tell when its actually doing it than you might think. I dunno but I can;t really tell much difference when it switches. Maybe thats just me.

Forget it , you wont see any changes in the Factory changes , you will need to get a Performance tune . Ford is very limited as to what there allowed to change

I have the Predators at 350.00 right now then you will feel what the SVT should feel like
