If you're saying that any of the 3D tables that use throttle position are subject to this, then that's not my experience.

If it were true all the time, then I wouldn't be able to run over a 1.6 load as this is the value at the 75% row in my TRL A&C tables (gear values are 1.84.) So, hypothesizing here, it may be a technically correct "fact" in isolation, but when added to a system, the result will vary according to the many other variables involved? Most particularly I'd guess would be the DBW table, where most have max throttle at say a 1.5 load or even lower.

I tested again today a bit (not logging, just eye-balling) and no to little spike. It's almost thrilling to see the boost simply climb and hold at maybe +.25 psi from target on a shift - this in 19F ambient. Looks like you did what I figured you'd do on the IAT table - I'm going to try that to see what happens, but I run Boost Dynamics at a 30% reduction both sides, and have max values at higher rpm in WGDC at maybe 40, so it may not apply to my setup.

I have a feeling some of these options for tuning boost response may be redundant - different path to the same result. Trying to figure now what the "best" path might be, or if it really matters.

Again and still, just loving the boost toggle.

No, just the pressure based boost calibration tables from what the data has shown me.
