PaulTF New Member 10 Member For: 8y 10m 21d Posted 19/09/15 04:55 AM Share Posted 19/09/15 04:55 AM Hey all,Quick question. Got an 04 ba running an 07 bf motor. I have 2 custom tunes, 8 and 11psi, through an SCT Flash box. With either tune it runs 8psi. Bog stock apart from this. Testing the boost solenoid without power, it doesn't boost. I'm guessing this means that without voltage, the solenoid stays open and allows pressure to open the wastegate.So, if the solenoid was faulty (not closing properly), would it then in turn bleed pressure and open the wastegate prematurely not allowing for full boost ie 11psi?I've ruled out boost leaks, spark plugs etc.Thanks in advance for your replies.

Car now thinks it is a Holden. Doesn't recognize anything associated with turbos. Link to comment Share on other sites More sharing options...

I find it hard to see that wd40 has killed it. I'd double check that it hasn't blown a hose off or something Link to comment Share on other sites More sharing options...
