So I called whipple this morning and after 45 mins on the phone with them the only solution they have is I can send my pcm to them so they can flash it to an older calibration file they have and see if that does anything... no guarantees... he mentioned no other mustang owners have complained about this problem but he was aware of a similar issue with the f150...
