In what way are they not alike?
1. Different Gas needs different tune.
2. Some cars leave rich, some run a little lean. If you put 10 GT's on a dyno you will get 10 different #'s.
3. I would not want some guy in Ohio who has 93 octane giving me a tune for a car in CA that runs on 91 octane and lives at a higher elevation.
Not to say it wont run on the chip. But I dont want my $170K car running on a general tune for all. Better to spend a few more bucks and get one that is exact to your car.
