Competitive eater Nick Wehry -- husband of women's champ Miki Sudo -- is facing bombshell allegations stemming from this year's hot dog contest ... being accused of cheating to increase his end result.
This year's fourth-place finisher was initially handed a score of 46.75 tube steaks eaten at Thursday's Nathan's Famous Hot Dog Eating Contest at Coney Island ... but after a recount, his total was changed to 51.75.
As we previously reported, Patrick Bertoletti won the Joey Chestnut-less outing after downing 58 weenies.
