on the subject of the chip i have been shopping, and found that more people like Diablo Chip than any other. I have many reviews, here are two reviews by people in CEG one on SUPER CHIP, one on diablo.

DIABLO:
Hey,
I have a 1998 2.0L Zetec GL ATX.
Takeoff? a little faster (not too noticible)
BHP? you can feel it but again nothing incredible noticible
Torque? can go up those hills better for sure... nothing supernatural though
MPG? i went about 100-150 KM more per tank
Shifting? this is where i noticed the most benefit. I have an automatic so
the shifting was pretty sluggish before. after putting the chip in, it
definately shifted at more appropreiate times.

-Adrian

SUPER CHIP:
It gave me about 10-12 hp and about 5 ft/lbs.
of torque. I did not notice any difference in MPG
though... Shifting is the same. Hope this helps.
