What they said. Tune will matter I'm running a tow tune from tyrant and don't see boost over 18 but I don't floor it either
I have 50k on my delete and as far as I know it's stock turbo at 175k miles my 11
My 2012 had a weight reduction at 130,000 and the turbo said no more at about 180,000. Mainly ran a tow tune which I believe is around 40 hp over and changed my oil every 5,000 miles.
Definitely makes a difference in the lifetime after adding power to it. However, once the weight is reduced, it's a lot easier to change the turbo IMHO.
