Datalogging

I was wondering if someone could look over my datalogs, I'm having an issue with pinging and loss of power from my 2010 Ford Ranger with a 2.3 Duratec and auto transmission. I've looked at them myself and I don't see anything really wrong, but something has to be off, the truck won't go over 73MPH unless it's downhill!
Also, how can I post my datalogs to other sites, when I try and link them to other sites all that shows up is a text file full of gibberish. like what I attached here.
