P59 Throttle Closing!!!! Help!!!

[AMGDON]

I have a 2004 Z06 that has been LS3 swapped with some goodies like cam, intake, & LS2 Stock Throttle Body. Car runs fine but at WOT the TB starts to close around 5k-6k even though is commanding 99.9% any ideas?

Take out some of the pid's that you are logging. You need better resolution to better see your problem. Try only logging throttle, rpm, mph, timing, cyl airmass, map, mass airflow freq, current gear, throttle source
