Hi, Does anyone know the stock boost pressure on a TC4EE1 Astra? I know I've seen it before in the Turbo Diesel Tuning pages but as there are so many pages it'll take me forever to find it!! Also, is the turbo a RHB4 or a RHB5? I'm sure it's a RHB5 but I'm not too sure - correct me if I'm wrong. Thanks in advance!

I think mine was at about 8psi before messing with it if I remember right. With them not having an ecu to monitor it though you can actually use a bleed off type valve to increase boost pressure. They're also very tuneable with them being a mechanical pump (after removing an anti-tamper cover just a flat headed screwdriver and locking nut to adjust the fuel / power).

Not sure on the turbo unit model ID.
