i am about to buy one of the raptor shift lights for my 2000 mustang v6 and i was wondering what should i set or how can i find out what to set the RPM settings at, the only mods that i have to my car is true dual flowmaster exhaust,

welcome to the forums. Just b/c you get a tach doesn't change your rpm setting. To change it you will need a tuner.
