Bill was the first to respond to your thread. I just sold my 2005 F-150 and the tunes made a huge difference. My favorite thing was the better shifting that the tunes provided. The extra power was nice, but I felt most of the power through the improved shifting strategy.
What were you expecting PHP to respond to? I see your first post was in july, we are in august, that is less than a month. Their email system is a POS, so I am not surprised that you haven't gotten a reply back from that, but unless you asked something there that you didnt ask here, Bill responded 3.5 hours after your first post.
Hope that helps with your decision.
