my dad has an 07 classic duramax....stock he was getting around 15....with the edge and afe intake....he gets 23-34.
HAHAHHAHHAHAHAHAAA!!!!GF's dad has an 04 dmax with a programmer.. He averages 16-17 in town and 24+ on trips.
Couldn't tell you how he figures it. I've asked him what he gets and that's what he told me. He has no reason to lie so no idea.HAHAHHAHHAHAHAHAAA!!!!
Thats the funniest shit I have ever read. Their going by the read out huh? Well its wrong or they can't do math cause a V-8 diesel will not get that unless they are going down hill with the a/c off drafting behind a 18 wheeler.
A programmer and the Edge will mess up the reading cause of timing advances and etc.
I assume that's a typo, b/c noone is getting 34mpg in a fullsize, let alone an HD....my dad has an 07 classic duramax....stock he was getting around 15....with the edge and afe intake....he gets 23-34.
this was calculated miles/gallons....not using the DIC.I assume that's a typo, b/c noone is getting 34mpg in a fullsize, let alone an HD....
Via DIC I'm getting roughly 15mpg. ~18mpg highway, ~13-14mpg city. Haven't gotten any tuner (yet), truck is 100% stock w/87k on 285s (~7%+ vs DIC). Am only on my 2nd fillup, so haven't started the new log in the PDA yet. Once that's started, I can give lifetime avg.
Diesel is $2.85 @ Flying J (reg $3.1x), $3.09 @ Chevron ($3.2x reg). FJ is about 5mi farther away, but between saving ~$4/fillup and knowing I'm not getting diesel that's sat for a long time, it's worth it.
I'll be interested to know how it may change once I change all the fluids and such.
If you want better mileage, gear down to 4.56, and replace the flowmasters with a flow-through muffler such as the Dynomax bullet because Flowmasters don't really flow that well. If you are running duals and don't have a X-over pipe, get one. Also replace the air filter with a Wix or K&N unit if you haven't already done so.Due to gas prices and such, im considering switchin to a diesel. What kinda of fuel mileage do you diesel guys get and hoe much do programmers like bully dogs and edge help?
