All I can say is HOLY CRAP! Coming from a 2000 6.0 vortex this set up is awsome! The truck doesn't even flinch! 70 and sunny about 70 miles from home and 12.2 MPG--NICE! I am grinning!
yep, when i went from a Ford v10 to a LB7 it was amazing. we made the same exact trip with the LB7 that we had made with the V10 just 2 weeks earlier, so it really was a fair comparison.
Bigger truck same 5er but better mileage. And power at way lower RPMs.
Maybe I'll upgrade the truck one day, but is it even right to trade a Duramax before hitting 100k?
