1st thing you MUST do before checking out any profile is use the SRS app to ensure your 'Max Angle' and 'Spike Filter Level' values are calculated correctly based on the distance between the center of your left/right actuators. The SRS app figures this out for you very accurately - all you have to provide is one simple measurement then apply the suggested 'Max Angle' and 'Spike Filter Level' across ALL GAMES.
Set it and forget it basically!

I have 3 PT-150mm actuators in a tripod (2 front, 1 rear) but these profiles will work just the same with 4 actuator (each corner) config, assuming you are using the SRS calculated levels.
I have 800mm between the top center point of left and right actuators so my values are:
Max Angle: 53
Spike Filter Level: 1866 Vertical and Vertical (I do not have dedicated TL platform)
Optional - I'm using AMC Filter 2 (softens impacts/curb strikes etc) - personal preference on this one, and this has to be done from the AMC-AASD15A controller itself.
I race 100% in VR, so if you need a little more motion, simply raise/lower the individual DOF sliders for Pitch, Roll, Surge etc. adjusting 'Smoothing' as you see fit for the feeling you like from your motion rig.
NB: Gathering Telemetry will sometimes show very high or very low values based on the track, and in these instances you will want to lower these Max Tel values.
Take Heave for example, at a bumpy track like Belle Isle or Sebring, you might see telemetry at Max 30 from iRacing in a GT3 car, but if we were to use this value then it would mean that for tracks with much less pronounced bumps, it may be difficult to feel the smaller changes in track detail.
So having a lower Max Tel value of say 18-20 will ensure that you keep detail across all track surfaces.
Similarly, Traction Loss, Sway and Surge are tricky as your telemetry gathering lap will be clean and fast, so the game telemetry gathered will be low here (maybe around -3/+3). Increasing the Max Tel value here will allow for a buffer to avoid having unpleasant jarring when you hit up on the max telemetry of the game when you do push the car beyond the limit. This is why it's important to at least gather some telemetry on a car you are tuning for the 1st time across multiple tracks and track conditions.
Pitch and Roll will almost always be accurate to the game telemetry, with the exception of oval tracks with high banked corners where you might need to change the Roll Max Tel values to compensate.
Huge thanks to Jeff Weaver for taking the time to help me understand the crucial importance of Telemetry based motion tuning.
The 'Max Telemetry' values to the right of the sliders will use some of Jeff's hard work, and if you want to start with a baseline tune, you can check out these values for different cars in his terrific SRS 2.0 Guide attached below. Even though it's for DOF P6 Platform, the 'Max Telemetry' values remain the same for any platform as they come from the game, and then start messing with the sliders to suit your own taste if none of the available profiles do it for you. This should save you a lot of time to start with baseline values:

You should be able to grab my profiles (and others) from within the SRS app. Mine show up as 'Sean' in the PT area - I'm always learning more about this system, so worth checking in for updated profiles, new info as they may have changed:
As of Nov 24th 2020 these profiles have been completely revamped. These settings are tuned for competitive racing where immersive, yet accurate and detailed motion cues without being over the top are the driving factor for me over pushing the motion rig to the max for 'big thrills'.
Nonetheless, they serve as a good guide and should create a really enjoyable motion experience from your PT-150/SRS rig.
Ok! That stuff out of the way, let's try out some iRacing Profiles!
