I have a 2013 stage 1 whipple mustang that I bought without the sct x4 tuner, previous owner didn't have it. I bought everything from whipple to upgrade to stage 2 including a sct x4 device but it won't read the strategy code and shows error 11020 when I try to program the car and won't connect. Anyone ever run into this? Whipple is saying I may have to have ford reset my car to stock before flashing or I have to send my pcm to whipple to be reset.
