As far as failure, I've found one case of either the resistor or relay failing....I like my odds But when the time comes for me to sell a kidney and get a Motec, I'll rip out everything stock I don't need and rely on the ecu.

The FPR will take care of most of the difference as far as tuning goes.
Mazda doesn't always do the best job of economy. I have a friend of mine, we went out and street tuned his Rtek one night and he got something like 28mpg on the way up to canada. Now, granted this was an n/a but I never got close to that when I had a ecu.
Bottomline is, using the stock Rtek map is a weak excuse for wanting to keep a voltage reg. Lower voltage means higher amps, I'm not sure why Mazda did it that way, but I don't think it's needed, therefore it goes away.

First time I've heard of a pump burning out for no reason, there must be a reason...... could be low voltage caused by a bad voltage reg
