Hi i have a ren 3 twin turbo with just an induction kit, chipped ecu and hks system.

Sometimes when flooring the acclerator the second turbo wont kick in at 4500rpm and some times is does, The boost gauge only shows 0.5 bar at the most which is a bit low i take it, and im sure the dump valve is no where near as loud as it used to be, could this be anything to do with it?
There was some kind of electrical wire hanging down the other day, it was a thin wire inside a bigger hose when i went to jack it up the wire had gone and i cant see where it came from. The car still sometimes boosts even know the wire has gone.
When driving the car around slowly or in low revs it chugs around alot and drives quite rough. There is also a strong smell of fuel from the outside.

If anyone has any answers it would be very much appreciated. thanks

 

I have the same problem, except the disconnected wire.

Dont know what it is!
