Question Motion doesn't seem correct on my rig. Any advice

Hi everybody. Can somebody provide me a little advice.

Im setting up my DoF Reality P3 Rig (with Traction Loss) and the pitch axis doesn't seem to be what I expect. Got the same, what I think is an incorrect output on multiple sims.

Consider doing a lap of Spa, I I drive down the hill towards Eu Rouge the rig is pushing me forward (as you would probably expect) and then as I climb up Eu Rouge the rig pushes me back. OK so far. However as I level off down the Kemmel Straight towards Les Combes, my rig is still pushing me back into the seat. As I hit Les Combes I apply heavy brakes but the rig doesn't pitch me forward. However the short straight down to Rivage doesn't seem to give me that same forward pitch felt earlier.
Just didnt seem right all the way round the track.

The rig seems, in most cases, to be simulating elevation and not forces due to acceleration and braking which is what I would expect to be simulation. All the way round the track the rig feels a little "floaty" if you understand what Im getting at

I wondered if it was down to the output from the game but the rig was the same for both Assetto Corsa and iRacing.

Don't get me wrong, I've never driven Spa track so don't know what it should feel like but the forces simulated on my rig just doesn't seem right. My axis are set pretty default at the moment because I'm just learning how to set this thing up to get the best out of it, however I do think there is something not right.

Can anybody help?
