Hi I cannot get my head round this am messing with my boost on my s2 on cosworth management. I want to take off my bleed valve to stop it spiking so when that's off I can not get anymore than 15psi so got a stronger spring for my actuator 18psi rated put it in and still only 15psi. So I bought a new actuator one good for holding 22-24psi put it on last night and still only 15 psi when I have bleed valve I can bleed it to 21 but it spikes to 26 and kicking boost limiter in anyone have any ideas why I cannot get it over 15 with no bleed valve
