Recently I noticed that my boost gauge was hitting around 15PSI.I took the car to the local mechanic / dyno place, he check the car and said “looks like your boost solenoid is faulty”. He said that he got the air compressor and put little amount of air to the actuator & it move fine. He bypassed the solenoid and connect the pipe from the turbo direct to the actuator. Then I was getting 6-7PSI.I bought a new Boost Solenoid and replaced the old one and reconnect the pipe back to normal. I get 14 – 15PSI. So then I did the bypass and connect the vac pipe from the turbo direct to the actuator, I get 10-12PSI….Ive check for air leaks but couldnt see any.Can someone suggest what’s going on with my car and how can I fix it.Thanks Link to comment Share on other sites More sharing options...

Skids4kids in the mid....not the bum like some Member 609 Member For: 11y 6m 22d Gender: Male Posted 24/09/13 01:51 AM Share Posted 24/09/13 01:51 AM Does the actuator swing arm assembly swing freely when some air is applied to actuator?Is the car hitting boost cut at all as in a rough ignition cut feel...over boost on a stock car is usually caught by around 8psi so this is really unsafe having 15psi come up.What does she go like lol?

I driving it without hiting boost as I dont want to break anything.There is no rough feel before or after boost Link to comment Share on other sites More sharing options...

Didnt do that before Link to comment Share on other sites More sharing options...
