You guys are being too nice to the guy trying to make it seem like he had anything to do with it based on the 1992 meeting that is backed up by one guy who:
Carey became president and CEO of Frito-Lay North America in 2006. In 2007, Montañez began telling his story in public, and the pair have made joint appearances at a number of public events over the course of their careers.
Appears to also be making money and some fame off of this story. Heck, there’s a movie being produced by Eva Longoria and there’s pictures of this guy at award shows. Fame, hobnobbing with celebs and money are a powerful thing. Also, from the same LA Times
article, it mentions all the proof that the Flamin Hot brand was already in test markets in 1990/1991 and rolled out across the country in early 1992. If a product is rolled out nation wide in 1992, his meeting in 1992 with the CEO had no effect on it.
