Last year I had an engine light come on while I was on my way home from vacation. Took it to the dealer and they said there was a problem with the Cat. They replaced it with one of the updated ones so the problem was fixed. When I got the truck back it seemed to be lacking a little power. Just had the water pump fail and took it back to the dealer. While I was there I asked the guy about the power. I Asked him to look back through the records to see if they Flashed the computer, sure enough they did. Has anyone else been through this?

Thanks
