Did you have to re tune your AEM with putting the new map in or did you just change it over in the EMS and call it done?

In the AEM you do have to set it to read the 3.5 bar map because it uses a different voltage range. But Its really simple because the AEM pro 1.0(software on laptop) Has different map sensor calibrations saved in. you just need to pick the right one. Its explained more in the manual.
