I was talking about a stock Duramax, read above.
i don't now about that health diesle keepin up with a Duramax. my Duramax has 380hp and 800ft.flbs. at the wheels. thanks to www.Fastspecialties.com but the good news with the 6.5turbo is you will have a fairly simple install. and you wont need to run a intercooler
