If rev early impreza turbo hard then release throttle pedal will cut out instead of idling, on rare occasion cuts out when pull up to a junction.

Would anyone have any ideas poss could be?

Have fitted new dump valve to make sure not that, cant hear or find any air leaks and no fault codes logged.

Cheers.

 

Standard dump valve?

 

baileys DV26

 

If you can see if you can adjust the VTA or change back to standard.

 

dont think you can on the baileys valve. is plumbed into front mount intercooler pipe work so cant change back to standard, was just a cheap nasty one on there before which came with front mount, seem to help putting this valve on but still not 100% right.

 

You could try blanking off completly. Then you will know if the DV is the problem.
