Dual boost

Hello, I'd like to set my boost to 1250 mbar (in low boost mode) and 1350 mbar (in high boost mode), but I can't. The value I'm getting is all the "quick spool" values. How do I do this?
the setting dual switch is well parametered
the problem is in boost the settings but I don't understand which one

Here's my SKL file.

thank's

Why do you have VTEC disabled?

How do you have the VTP input wired?

Hi, no VTEC because the engine is new and still being broken in. / VTP wired to a grounded switch, like an AC switch for example; the vtp sensor correctly detects the button when it's on/off

In the datalogs you do not appear to be really going wide open throttle and attempting to go into boost and the turbo may not yet be spooled up.
