Hi,

We have an issue with our 2006 Mustang GT.

The car was running well for a year then all of a sudden it started to loose power at WOT.

mods include:
SCT Tuning
Steeda pulleys
Steeda CAI
Ford Racing intake manifold
SW off-road long tubes and cat-back

The car has brand new O2 sensors, and MAF.

Here is a video of few wot runs. The engine revs like normal when the clutch is depressed.

That datalog file is nothing but giberish to me. I would check your fuel pressure - make sure it's not loosing any at WOT or heavy load conditions. Have you checked for codes? Has the message center displayed any warning about fail safe mode?
 
When you say WOT, do you mean sitting still in neutral, or do you mean while actually driving the car with the RPM's at least at 4500? You will most likely need to take the car to someone with a more capable scan tool that can read all sensors aside from the SCT tool that you are using now.
