Seems my car is gone wrong again lol.
Now im suspecting boost controller but could be wrong.
Car did run at 1.0bar
Car now runs 0.45 mid rev range peeking at 0.60 as the revs rise (im sure boost leak would indicate a high initial peak and then a drop)
Car runs the same boost with controller switched on or off (always ran the above with controller switched off before)
Last week i had same problem but 20 mins later full boost was back (think this may rule out boost leak)
No hissing sound from engine (surely boost controller set at 75% ratio would hiss like a snake under full throttle if air was escaping)
NOT in saftey boost as car cannot boost controller overides this funtion
Am i right or wrong?
Test 1 will be to disconnect boost hoses from controller, install boost jet, reconnect origional actuator plugs and see if i get higher boost?
