Yes, it might have taken a while to get the design right.
But lets keep the whole thing in perspective, the only thing going on, as they disclose on the web site, is that they are reducing the pressure that the ECU percieves. The change absolutely has to preserve the linearity of the signal. The slope of the signal can be changed and its 'zero' Y axis intercept or dc offset can be changed as well. The ecu is driven by the changes in the sensor signal and really does not care about the dc offset. They engineered a solution to reduce the slope of the map signal and also fixed the dc offset.
You will have power similar to a ECU mod. But the point that I was making is that the boost lag will still be there like the ecu mods. Thats the nature of the BPC valves.
Do you have a MBC combined with the T4boos4 unit? 20 PSI seems real high and I thought that they suggested a 4 PSI increase. Perhaps the increase is much larger than advertised. Are you seeing 20psi on a calibrated boost guage? If you had a HOT turbo engine, perhaps it responds with higher boost.
"""Features:
Add up to 4 PSI BOOST in 15 Seconds
<snip>
Raises both boost and over boost fuel cutoff up to 4 PSI. """
