This all assumes your ranges are pristine.
According to FToP, the folding is mistake, because you choose 0 EV move instead of +EV move (EV=your PFR size+dead money).

According to "hand range" folding is correct, because calling costs you more, than equity in pot you have. Against entire range, calling has EV<0.

You can't use FToP because you don't know exact hand of villain. With less accurate info (ranges instead of particular hand), decision can change.
