Turbosmart Plumb back DV - which spring?
Hi.
Added a set of Turbosmart Plumb back DVs to my CP-e chargepipe yesterday. But I have som issues with boost pressure dropping when reaching about 12.5 psi. It drops about 1.5 psi then increases again until it again drops the same amount. The problem is bigger when putting the car in 3rd gear or higher and then WOT. If I accelerate normally from 1st and 2nd gear until 6000rpm the pressure holds better. A bit strange I think..
I have checked all hoses and clamps and cannot find any leaks. Could it be the green spring being to soft? What springs are people out there using? I boost about 17 psi with a Cobb stage 2 sport OTS.
