BEN189 Member 96 Member For: 22y 2m 12d Posted 17/03/12 08:19 AM Posted 17/03/12 08:19 AM Actuator I reckon, especially if it has been tuned for more boost

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.

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.

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.

The actuator hose was connected straight to the front housing and the soleniod hose was connected back to itself.
