^^^Yep. You're likely running lean at WOT, and the ecu is cutting back ig timing...
as knock sensors are doing their job and detecting the lean condition. I'd try not to drive it at full boost until you fix the underlying issue(s).

And if it is running lean at WOT, check the easy stuff first...
Remember SteveJ's mantra on car repair:
"Check the easy stuff first."
Lean conditions can be caused by something as easy as a clogged air filter or fuel filter, or one (or more) of your injectors may be partially blocked - run some Techron fuel injector cleaner in your next tank full of $$$ premium.
Let us know what you find.

the air filter fuel filter fuel pump, o2 sensor, plugs, wires, rotor and cap are brand new, the idle mixture screw was tampered with in hopes of solving previous rough idle problems fyi
