Use the WGDC and Target Boost maps properly, column spacing allows resolution
Plus closed throttle is under vacuum, not 10psi boost in manifold

thanks! Did this for reason we had too lose wastegate preload and boost come too late and spool was slooooow. So i turned targets up in shift regions, but it didn't help...
But at the map I've loaded and charts, we already have adjusted wastegate and it spools like we want, at desired rpms (not too late, not too early) for stock engine life...
