Hi all
i have a mk6 escort with a fiesta turbo engine and managment.

but the fooking thing will not boost.

i've checked the actuator and seems to be ok. nice and tight

i've done a t3 conversion using erst manifold and the turbo is brand fine new never been used.

before the engine came out of the fiesta it prodused enough boost to make the dump valve work by just revving the engine, now it will not. If I rev the engine quite hard the top intercooler pipe sucks itself shut.

any help or tips would be great.

cheers,
Phil
