Tial Wastegate question!!

Hi,

Just had my car at the dyno to adjust EFI settings.
The boost was close to 1.2 bar on DynaPack system. The installed Andial Boost gauge show close to 1.1 bar.

The 46mm Tial wastegate has 1 small red + 1 big red spring. According to Tial this should be 1 bar combination.

Is this common that the spring may vary ?

I would like so run safer and boost at max 1 bar.
Is it recommended to install a softer spring like 0,7 bar and install boost controller?

There is installed a boost solenoid operated by ECU, but this is deactivated since spring already is sat at 1 bar (closer to 1,2 aparently)
Maybe install 0,7 and activate this solenoid ?
