Just a question with OBD2

The ELM can reset some ECM error codes to turn off the Check Engine Light. It can read many different values such as engine temperatures, RPM, speed, fuel/air ratio, timing advance and so on. It cannot override the factory programming of the ECM. You can see many parameters of what the engine is doing, but can't use the ELM327 to modify thse values. It will not affect the performance in any way. Software such a Torque will basically allow you to have extra virtual engine instruments, and read diagnostic codes if there is a problem.

Exactly what i was wanting to hear... Thank you for the clear and direct to the point answers. So i guess i'll have to leave it plug in. :)
