Full power use on T/charged engines

[WX Man]

I operate a PA31-350T. We routinely take off ax MAUW, and therefore use full power on take off, which equates to about 46" MP.

I have recently been advised by another pilot that although this is within the limits of the 49" MP dictated by Lycoming, operating the turbochargers at full whack can damage the engines, possibly leading to an engine failure at some point in the future.

Any thoughts?
