Default Boost limits on the Profec B??

I know it depends on your WG spring, but I can't find this info on GReddy's page...

Is the limit for high boost, WG spring rate +1.0 bar? So on a .45 Tial, 1.45 bar max with the Profec B?

Just curious so I can plan what WG spring I need to pick up.

Also, what is the MAXIMUM boost the Profec can regualte overall? 2.0 bar?

Thanks, Guys.

Anyone know what the percentage is? I need to know the percentage so I can calculate what the MAX boost I can adjust it to with the .45 bar Tial...

with a 7psi spring i ran 17psi with the high boost **** on 3o'clock. still had a quarter turn left. I'm thinking it would've stopped at around 21-22psi
