Unfortunately i didnt make such complex tests with the original actuator, i worked with the forge also i didnt have a boost gauge fitted(which i should have had for accuracy) i watched nanocom inputs fuelling comparing different setups... my tests were mainly to see which setup is better for the driveability and the best IMO is WGM + MBT and actuator a bit more ''relaxed" than the factory setting or the WGM with actuator at factory setting, the original one would be at around 15 threads left out that way, i have the original in my garage so i'll measure with a bycicle pump which has gauge where it starts opening but my presumption is that it's around 0.8 Bar then it opens more according to the load, it acts on boost like a thermostat on water temperature, progressively untill it's fully opened.... simply shortening the rod increases final boost but makes it jerky as the travel of the wastegte is reduced but with longer rod and manually controlled boost the boost curve is smoother as the wastegate's travel is more progressive.
IMO the best will be when Offtrack will work out a remap for the WGM management as to work well with "relaxed" actuator
