i installed a bleed type boost controller (bad ino) im running every thing completly standard in my 95 wrx and when i take the boost to 14 psi (1 bar) its fine for a few seconds and then its like the engine dies for a split second and then picks up again for a few seconds and then does it again.but if i sit at 0.9 bar its fine. any help would be great

cheers jonny
