Before I ask about the Jet Module I'd like to state that no one under any circumstances should anyone buy a so called "chip" (resistor mod) off ebay for $20. They change your air to fuel ratio and at best decrease performance by sending too much fuel and running the mixture rich. I recently tried it. Trust me.. I got WORSE mileage and no performance gain at all.

Anyways...
Ive got a 94 xlt 3.0 and Im not sure I can use a Jet Module because my truck is pre 1995, which means I have a OBDI port instead of an OBDII port.
Does anyone have experience with this product?
