I would like to ask you guys at what rpm do you feel the turbo boost to engage.
After a camshaft belt change at 88.000km (50k miles), it feels to me as if the turbo boost is engaging too late - like around 3000 rpm.
I own my S60r now over 13 years and I would swear I felt significant power increase around 2000rpm. Overall, when it hits 3500rp, the power seems to be adequate.
Many thanks for any information or hints.
