Logged a NOS pass WOT is only 79%, why?

[Redline MS]

We are dialing in a 2005 H/C C6 with spray and logged the following log. I know that the reported TPS is usually 88% at WOT but why is this car reporting no more then 79%??

Is there anything with the 05's where the PCM decides to back throttle opening to a certain max value?

Is this not an issue?

Thanks

Here is the log;

You need to monitor ETC position not TPS.

You need to log ETC position %, not TPS SAE on your car.

I figured they where different but I always at least remember seeing in max at 88%. I'll change the PID.
