2015 x19 flashed 200 SHO (300). I’m running a hill signature 4 26 pitch. Tourney loaded heavy! live well full 75 no problem but really really bad steering torque at that trim and speed. I can come down to 69-70 with very little trim and it drives like my truck Am I to high or to low or is this a prop the issue. Only running a 6 inch plate.
