stock duramax
 

what kinda mpg numbers yall putting up? and what mods do you have

that all depends on a lot of factors, what year/model of truck are you talking about, and what do you mean by "stock"?

BONE STOCK I have seen my friends get a average of 14-16ish... With simple mods, exhaust/chip, they are close to 20 mpg if they drive it nice :tu:

What year is your truck?

I dont personally have a DMax. I was basing these numbers off my friends who have LB7's

when my truck was stock i got 15ish around town and about 20~21 highway. now with my EFI live tuning and other mods (signature) i'm around 16~17 in town and 22 highway. this is unloaded. haven't done enough towing to get accurate numbers, but the last time i think it was around 14 with EFI Live. no stock towing numbers, sorry.
