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 ?
I have a Tial as well with 1 bar installed. But the pressure was the same 1.1bar as with the stock WG. The reason for the boost increasement was the change of the headers, which was discussed on other threads. Headers like B&B, Fabs etc. will end in higher boost level
