Performance Chip

I just bought a 03 FX4 5.4L & since it already has a K&N filter & Flowmaster exhaust, Maybe the guy before Me put a chip in it. How can I tell? Where do they go? Are they any good?

Here's one on fleebay

Those particular "chips" are a scam, they will be a resistor in the box that just makes the engine over fuel. IIRC they tie into the MAF or in that general area.
