Hi so I have a 2008 Silverado 3500 Duramax. My turbo is going bad and I was looking into some other forums and people were saying that having a tune, cold air intake, and straight pipe often puts stress on stock turbos. So I guess my question is has anyone gotten the Garrett Stage 2 Turbo? Can the turbos be switched out with ease? Do I need to upgrade anything else with a stage 2 turbo? Thank you for any help.
