I get this screeching / squeeking noise when I'm on maximum boost (0.8bar). On other boost level's it's fine but only on 0.8bar. I don't have a boost controller but its not spiking. Can anyone tell me what's going on? Is my turbo going to die soon?
Current engine mods are 3" turbo back, Blitz front mount, 2 BOV's (Blitz and stock), A'PEXi Power Intake, Walbro fuel pump...
