Hi Mr Logger,
Welcome to F-150 Online.
While the Tweecer does indeed have some benefits for those who are actually capable of doing their own tuning, that is not something you can just bolt on to your vehicle and go - in other words, it's not the type of device you are looking for.
We *do* provide a chip for your vehicle - because it is a 194, you cannot use any type of hand-held tuner, as it is the older OBD-I type of vehicle and thus has no OBD-I port - so you will need to use a "traditional" type of performance chip. That is not a problem, and it will delvier the same performance tuning, it's jsut the type of decide you must use and connect to your EEC-IV computer's J3 port.
For more details, jsut give us a call at our nubmer lsited below & we'll be happy to help.
