I cleaned my boost solenoid yesterday and defiantly noticed that its not cut out anywhere near as much but is still not holding pressure fully.

Should run ~12psi I think.Be careful though. If there's fuelling problems you don't want to lean out and detonate.Probably better to get it checked out properly if the simple plugs etc don't fix it. You don't want to lose your engine...When you say it has a flash tune is that generic? If so you may be best going for a proper tune to see if your pump and injectors are maxing out anyway.

It was been tuned with one of the handheld tuners. Cal3 or something. It's going in for a service next week so I'll see what they think and get a check up. About the hose running from the solenoid, if remove that it will make more boost? Obviously not good for the engine though.

riptide Member 733 Member For: 14y 4m 6d Gender: Male Location: Auckland, New Zealand Posted 19/03/12 07:42 AM Share Posted 19/03/12 07:42 AM Yeah, the boost pressure through the solenoid assists the opening of the waste-gate. If you disconnect it it will take more exhaust pressure to open the waste-gate. It won't open cleanly though and the boost won't be quite as steady. I prefer an electronic boost controller. Gets the pressure up quick and holds it nice and stable.A good tuner can check what's wrong with it fairly easy. Maybe easier than the guy doing the service because it will be hooked up to monitoring gear for the fuel pressure and it may be logged also along with afr's etc. Link to comment https://www.fordxr6turbo.com/forum/topic/79336-losing-boost/page/2/#findComment-1211758 Share on other sites More sharing options...

Gasman Ford Nub Member 412 Member For: 14y 1m 16d Gender: Male Location: Gold Coast Posted 19/03/12 07:04 PM Share Posted 19/03/12 07:04 PM I dont think I explained properlyI plugged it back into where it was supposed to be, back into the solenoid.For some reason it had been bypassed. The actuator hose was connected straight to the front housing and the soleniod hose was connected back to itself.
