Out of countless hours testing tunes until 1:30 in the morning, this lope tune emerged for LBZ's! The lope is very consistent, in this video he is switching through the tunes, that is why it comes and goes.
In this video you will also hear the truck turbo winding up like on the Fleece turbo video on youtube that nearly every Duramax owner has seen. This is done with EFI Live tuning and truly sounds like a jet engine about to leave the runway.
Finally the deep rumble you hear is also done through tuning and removes the stock "hissing" noise while idling and brings back that true diesel sound. This feature also quickens EGT cool down when the truck comes back idle.
Custom EFI Live tuning by Longhorn Fab Shop.
