So i want to update my sct x4 device.. but i get this ominous message to return my car to stock.. i have saved the stock tune file on my pc.. i dont really see a reason to return the car to stock before upgrading the device... wouldnt the procedure be : upgrade device, load stock tune, load costume tune.. the sct x4 seems to have a different memory space for your stock tune as opposed to the custom tune.. am i missing something???
