Hey guys, not sure if this is the correct place to post so please feel free to move it. When my engine is cold my turbo will whine like crazy at the slightest hint of boost, but give it 5-10 minutes and it's back to normal. In those first few minutes, it will boost to max 2psi then after that will boost up to the 12psi. But when I'm not on boost the gauge will sit below 0. The car is stock, other than a FMIC, Coils Packs and Exhaust. (RB25DET NEO, R34 GTT) Is this a leak? Or is the turbo on its way out?
