| Load the stock tt tune from the 'File' dropdown menu and make sure it has selected the 370cc injectors. If it is showing 270 injectors you have the NA tune loaded, so reload the tt tune till it reads 370cc injectors. Your 'check engine' light will be on. Turn off ignition and then on again (check engine light will be gone) and you now have an oem tune. Connect Zemulator and make changes to injectors/intake, write to Zem and note 'check engine' light. Turn ignition off/on and 'check engine' light should be gone, new tune should be loaded.
