Fried pcm
So i towed a trailer these morning so i flash to a towing tune and truck ran fine till i shut it off, tried to restart all i received was a click. I moved fuses n relays around, tried to jump, tried to replace battery. Finally i found a dealer to take a tuned truck in under warranty, mechanic hooked up to reading tool and said pcm was blank, asked me to bring 2nd key so he can try to re program and if that doesnt work have to order new pcm. Can that happen after 25 flashes? Could i have had a bug in my tune? Or am i just un lucky? 3.5 ecoboost

Sorry but that was painful to read. Please use punctuation and proofread before you post.
Let's start with the tune. What is it? How long have you had it? Did you try calling them?

Ditto, I've tuned mine hundreds of times between the different tuners, dyno tune and now tuning it myself with HPTuners.

As to the truck question. My PCM malfunctioned in my 2012 ecoscrew. I had no after market tune. Replaced / repaired under warranty. Was a long process as they had to copy previous installed service codes ( I think ). I'm sure this would be an expensive but necessary service. Not much help other then to say problem went away. Good luck.

This is a forum about trucks not English 101. Of note, generally "proofreading" is performed by a third party who circles of marks the errors and makes correction on the copy or proof.

I'd say you just have a bad pcm, lots of chips inside that could go south without warning. I've changed tunes on my truck at least a hundred times and no problems.
