Bricked PCM??

You don't explain what you have very well.

The Speedometer, Tachometer, and Check engine signals from the LS1 harness are connected to the Dakota digital gauges main controller to feed the gauges. If a code or issue arises, the controller then will determine what code or error it is and flash it on the screen it has. Dakota Digital offers units that they call BIMS that tie into the main Dakota controller. Each BIM uses its own sender for things like Boost or fuel pressure and they all send information to the main Dakota controller which displays the added options on the screen and gauges. Being the Dakota controller is receiving and sending signals, could this be the interference causing the HP tuner program to shut down?

Do they connect to the ALDL data line? If they do then yes they can interfere.

They do not connect to the ALDL data line. They connect directly to the PCM pinouts.

Here is a illustration of the wiring on the Dakota Digital controller. Dakota wiring.PNG

So I recd a response from Dakota Digital. It appears this is the issue. They recommend turning off the Dakota Controller when programming. Dakota_LI.jpg

It appears this little tidbit was missing from the original post...
