I just bought my first powerstroke today love it but I believe it has a DP tuner on it.. I googled the name of what is on the knob and it came up as a DP tuner... it is a 6 position however I bought the truck from a dealer and he doesn't know what it does...
can you guys tell me what each position does or how i can figure out??? I've turned it and cant tell any difference? if you turn it all the way one way it seems "slower" then the other but the other side doesn't blow black smoke out?
