[QUOTE="ALBundy, post: 141617, member: 15"] To further add on, with regards to the different air density, temperature and etc...the air mass sensor will take care of that. For instance when you are driving in a colder climate, the air mass sensor will send a specific reading to the ECU (air density, temperature and etc), and the proper amount of fuel will be injected into the combustion chamber. Remapping an ECU will not take away this ability of the ECU to varies the mapping to cater for various climate conditions and hence...we always feel the car to be more powerful at night where the air is denser! So yup...its a NO-NO for both A and B. [/QUOTE]
