Pedals deadzones

[DarXtreme]

Hi! I have a problem with my GTR2 with the P&G mod: i have to press pedals from 10-15% pressure to have an input in game. I have 2 installs of GTR2: One, based from vanilla game, with only the P&G mod, and one with ,based on 10th year anniversary patch, with some modern mods. This one have no issue, as soon as i press the pedal, the game receive immediately the inputs. My pc has Windows 10 and my wheel is a Logitech g920.
How to solve this annoying issue?
Thanks in advance!
