hi ive got a fiesta turbo engine in my xr2 running ofab managment its not chipped or anything running a standard t2 the problem is when it boosts it goes to 1.2-1.4 bar which i know is not right . i thought it was the actuator changed it but still does the same thing does anybody know what it could be ? cheers

 

hello mate i also have an xr2 turbo, does it hold the 1.2 bar? i know it wont when the ecu trips out but is it a surge or constant? you could just adjust it down on the actuator and it should be sweet

 

yea it holds till the ecu trips ive adjusted the actuator right down but still did it ive changed the actuator but it still does it

 

First thing I would do is run a pipe directly from snale (turbo compressor housing ) to the actuator , therefore bypassing all the electronics and see if this drops boost , if it brings it down massively then you are either looking at a stuck boost solenoid or faulty wiring from ecu to solenoid valve . Would then put it back see if you can borrow a different valve then if it still overboosts , if it does then will have to disconnect ecu and check continuity from solenoid valve to ecu connector .

Hope this helps

 

you might have a hole in the vacum pipe between the turbo an actuator
this would make it boost more then norm hope it helps
