Cooling fans running at full speed after tuning

[Robisonjon2891]

I have a Silverado 6.2 and if I install the Diablo tune after one or 2 uses my cooling fans will start running at full speed and will not stop u til about 2 minutes after I turn the engine off or put the factory tune back on. Has anyone else had this happen to them.

I did the diablo tune with the 4 cylinder mode off the speed limiter off 20% throttle boost also
the attachment files should be here also

the only fan related change in this tune is where we upped the target fan speed up to 30% of total power in the lower temp cells.

Load this, it has the fan changes undone from the tune, and let us know if that resolves the issue.
