Overboost City!

[built2redline]

I had a boost leak at the manifold, because of a few loose bolts, these are now tightened and the car feels strong, however its boosting to 10psi constantly when before it was boosting to 5-6psi.

problem being in WOT when it reaches 10+psi when cold it cuts out at about 4000rpm and drops boost altogether (sort of like hitting the rev limiter).

and after changing gears all is fine again.

now the car hasent been edited yet and is going in for the edit and custom tune early in the new year. will it be fine untill then if I drive it sedately or should I be a little more worried.?

I also noticed that before this started happening the exhaust tip had a black sooty colour(which may mean it was running rich?)

and now it has a light grey colour. does this mean its running lean?

Mate it is worth getting soughted before you get edited under warranty. It could be a range of things but the actuator may not be controlling boost as it should and if this is the case it will only get worse the more boost you try to add.

as above man.. its worth gettin checked out before u start modding it.

Sounds to me like they might have dis-lodged one of the wastegate vacuum lines while they were in there tightening your manifold.

Just have a quick check around the turbocharger area for any loose lines.....

Hope this helps.
