I emailed Mike at Performance Products inquiring about the availability of a Superchip for my '02 FX4 Screw. He told me that Ford had not given Superchips the program for these vehicles yet, so the chip was not available.

I sent my ECU to Superchips last week so that they could read the programming and create a chip for it.

Mike at Performance Products called this morning to let me know the chip is ready, I should receive it by the end of the week.

So, in case anyone's looking for a Superchip for the '02's it's available.
