Easily create a more efficient turbocharger with a simple compressor wheel upgrade. When we talk about a turbo's maximum recommended boost levels, we base that on the RPMs the turbo needs to turn in order to create said boost. When you increase boost without increasing RPMs or drive pressure, the load on the turbocharger is the same for the elevated boost as is was for the original lower boost number. The best part is when you run at lower pressures, like you would in daily driving conditions, the drive pressure/ boost pressure ratios are always lower, which should in turn result in longer turbo life, not less.
