hi all, basically i have had my g40 now for about 6 months now and only judt got it on the road, the engine has had alot of work done to it by the previous owner, the thing is he has done a pipe work which i have never seen on any other g40 and i cant seem to get my head around what advantage it has plus the car is only running 0.5 bar of boost. here is the pipe it runs from the back of the block on the breather onto the boost return on the supercharger.
should i keep it or get rid of it or any help as i have no idea why it would of been done.
