I would assume its for the lack of wastegate control with no cats where you could over boost. I tune Mazdaspeeds and I know that if you don't run the right maps with them the car loves to overboost and just run havoc. But theres a shit load of other reasons not to run the carless without the map because of fuel issues, timing, and shit whatever else.
