Not sure if this is the problem with every wheel (but from steam forms i think it is), but i found out the issue. I set ffb to 100 in both game and t500 control panel (only for testing what each force ingame does).
I turned on the clipping tool (kinda a clipping tool) its under game options/ game/ HUD / clicked it over from: none/min/full/ telemetry. Once i had telemetry running a line graph appears on the upper left hand corner of your screen and lets you know when ffb is being sent to the wheel.
This is when i found out the issue, with all the forces maxed the graph let me know that almost no forces where going to the wheel when driving in a straight line (wheel straight) but ohh baby did that change when i turned the wheel. The line started going all over the place (I felt the gear changes, some bumps, etc) but only when the wheel was at a angle. I took the car off road and with the wheel straight felt nothing 100 ffb set in game and nothing (crazy) and very little data was being sent to the wheel, but when the wheel is in any other position then straight the wheel is being sent all kinda info, i.e ffb. It seems that even with dead-zone set to zero in game their is still an artificial dead-zone with the wheel. I'm going to continue to play with this
