TD Boost Problem

[Adam25]

Ive got a 1.7 turbo diesel corsa and ive fiited my boost gauge and bleed valve today but i cant get anymore than 10psi:confused: I think its got enough fuelling as it smokes on boost and it does seem quicker but even with the centre of the bleed valve out completely it still wont go over 10?

remove the cover on the top of the engine, does it have a saftey valve?

is it an izuzu engine for a start lol

[Adam25]

Its got a n/a inlet on it and yeah its an isuzulol

Take the actuator pipe off,.. see what you get then, if that don't work your wasteb gate might be leaking a bit..
