I have all stage 1 buschur on my car except a manual boost controller, because I'm running 91 octane. I just installed my SAFCII with buschur settings and my boost had been spiking all the way up to 1.4 bar (20.4PSI) then tapering like any normal evo. Would it be safer to run no MBC and sometimes spike to 20 psi, or run a MBC at 19 psi with no tapering?
