I have a friend who is going to sell me a Pro-M optimizer, i've heard it's supposed to be a good upgrade over stock but we have a problem,he got it from e-bay but it's still new.
he doesn't have the part number or anything telling us what year of mustang it it for except that it is a 4.6. i heard that 96-97 is not compatible with a 98.

the only number I have is off the maf 00A2579 if this says anything. question is I can get it for 100 bucks, (originally 350)

is it worth it to buy it? can it be reflashed or whatever needs to be done to work with my car?
