TQM issue

[niceguy]

I am tuning this 07 nbs Silverado with the GEN 4 5.3. For some reason whenever the rpm's go above 6000 it goes into some kind of protection mode.

Everything was disabled in the TQM section and engine rev limiter was set well over 6000. Any idea what could be causing this?

Here is the file

The only thing I can see in your file is the Cold Engine RPM limiter is still at 6K. Might try bumping it up to 6.5K

Set the Accel Thresh table to 0.

Hmmm. The Silvy's have the accel based stuff enabled...
It shouldn't be reacting to that but Russ may be on to something here.
