Programmers and chips are available at every turn..... I do auto repair for
a living... I've played with some of this crap..... all of the crap that I
have played with has been crap.....

Your cars programming has been designed to minimize exhaust emissions.....
tread carefully here because we are discussing the air that we all
breath....There may be a small increase in gas mileage to be gained from one
programmer or another.... if a gain is realized, it is likely that this will
come at a cost in tailpipe emissions. Totally unacceptable....

There are gains to be had with modified programming.... either in
performance or mileage.... OK for a "toy" that is seldom driven but for a
daily driver...... Imagine this..... 50 people pass a streetside trashcan
each morning. Every last one of these people carry a Starbucks paper
cup..... Five of these people put the empty cup in the trash can.... the
rest throw the cup on the ground.... Draw your own conclusion....
