Actually I can still hear it slightly at exactly 2200rpm. I believe that this fresh new oil (especially diesel oil) helps the turbo because before it was way louder. I asked my mechanic about it once and he said that if the turbo whistles there is something wrong with it (which I don't believe). Is there a way of getting more power at lower rpm from this engine? I would love for my turbo to start spinning sooner.

Thanks
