My controller I use for PC gaming is a generic Ps2 to USB adapter. Usually on controller you can't tilt and turn at the same time while using the d-pad. But using this controller, I noticed if you map the turning and tilting forward/backward to an analog stick, it works flawlessly. Now press the analog button on the controller (it will turn off) and now the controller will set the d-pad as your analog. By some magical reason, it now works fine and you can abuse that 360 diagonal flip to your hearts content. Hope this helps!
