[CROOKY]

hi

can anyone help me im at my whits end my93 wrx wagon will not boost properly the car is standard apart from a dump valve and i have changed the boost solenoid pipes to silicone apart from the one that goes to the air box as it has a restrictor in it the main problem is that the fuel is cutting out at between 0.7 and 0.75 bar according to the gauge is this right i have been told the car boost should cut at 1.1 the standard actuator is adjustable can i adjust the boost using this.

i really hope someone can help me

I'll probably be corrected here lol, but as far as I'm aware the standard car boosts at 0.8 bar - also have you cleaned the boost solenoid out?

plugs or coil packs.. try cleaning / replacing plugs and running 0.6mm gaps.
