No I'm not surprised by that at all, as long as the chip is connected its programing is going to effect the stock computers programing.

You really need to look at the computer itself, it is probably a chip plugged into the back of it. I'd be kinda surprised if its not. However it may just install in-line style with the computers main harness connector, say "unplug harness, plug chip into computer connector, plug harness into chip"? Reverse to remove?

Either way simply removing it (however its interfaced) will/should remove its programing at the same time allowing the computer to operate as stock, but you will have to look. If noting else get us the part number off it.

If its not external then yea you need to have it flashed by ford, myself I'd just pick up one from the bone yard for your model for 50 bucks and keep that one as is.
