the truck in my sig 99 F250. As I stated before its had 2 owners over the past 19 years not including me, it was never driven hard always easy all the time. I drive it easy also, its bone stock besides a cat and muffler delete I had done to the stock exhaust, sounds pretty good. Last week after I had the exhaust done, I asked my dad to rev it up in park so I could hear the exhaust from the back. I kinda freaked out as he hit redline and it bounced off the rev limiter twice before I yelled for him to stop. I'm pretty certain the engine has never hit the rev limiter not once since its new. The engine sounds fine, drives fine, but could that have shortened the life of the engine or caused any damage? I know the 7.3s are pretty tough, its never been chipped and is stock besides the exhaust, but I just want to be sure.
