Any Insight on this? The 93 tune is great by the way, i got on it a little not even from a stand still and the tires were roasting 35x12.50x20 at that !!!

Here is the file

I just updated from the 23r to the 25r update that came out on 8/25 and my truck has a substantial loss In low end power.
I had the diablotune and that is what I loaded back on after the update was done .
Has anyone else experienced this after revision update to the latest?
