It is because the tune that other people post are only for reference. You are not actually supposed to run them on your car expecting perfect results.

Too many variables. Example, say someone has a not so perfect IAC valve. If they compensated for this in their tune, and your IAC works perfect, it could in turn fall flat on it's face or run abnormal because of the setting the tuner compensated for.

The only safe tunes in my eyes are the factory ones, and only if you have a factory setup with no modification.

No prob, for the best performance get it dyno tuned, this way everything down to the are which you live in will be fine tuned to your motor :)
