Hey Dazz nah I know you don't need the update to change my diff but I don't want to constantly shift gears sequentially as it is my daily drive and hate it when in traffic. Also the speedo might go out a bit as well so rather just have the security of the flash tune update. Plus I just had a thought with my custom tune being tuned for my car as it is now if it will affect the power distribution due to shorter gears?
Will just try and wait until the ZF update is released
