Loss of boost?
Afternoon all,
My GB270 has lost boost and hoping someone could point out the likely causes. Using an OBD reader it's showing peak 7psi, holding at 5psi. I think the GB270 with PPP should be 1bar. I have no fault codes and no obvious issues i.e. strange noise, split hose, smoke, etc. It was fine one day then took it out and just felt sluggish...stuttering in 5th gear at 3000rpm. I'm thinking air leak, boost solenoid or actuator. What else could cause it? Faulty MAF?What would be your first go-to check?
TIA Matt

clean out boost solenoid first , a bit of carb cleaner will do the job , reset ecu after , disconnect battery pump brake pedal about 30 times re connect the battery and see how you go
