Hi all seem to be having a great deal of trouble with my daughters 1996 subaru impreza since the day she brought it. The problem is that it will not boost properly, will only boost up to 0.5 bar even with the Z4 after flooring the throtle in third gear almost like it wants to go but it's being held back all the time. It's had all new pipes, my old turbo off my scooby(known to work ok),new turbo control unit complete(left hand side under bonnet)have tried Z4 & U8 plus my Z4 ECU no difference in performance. Also had a new maf sensor, new air box with filter.
any help would be good thanks Jim
