hi folks, need help with this caravelle of mine.
its a 1997 p reg 2.5 ACV engine and has no low down torque but once you get to 2000rpm it takes off.

here's a list of what i've done:-

the turbo actuator rod is free,
i've had the pump timimg done and fitted a new air mass meter.
the EGR valve is ok too and i've also fitted a new turbo pressure control valve N75 but can anyone tell me which way round the pipes go?

i have a blue pipe coming from the actuator to the bottom of the valve (as it sits in the car)
a red pipe coming from the compressor side of the turbo to the top of the valve
and a black pipe coming from the air intake to the middle of the valve.

the duty cycle for the boost pressure valve is also ok.

anyone got any ideas?
