New truck prob with mpg's need input
 

Ok so I just bought a 05 ram 2500 cummins. It has a 4 inch lift( so the last owner told me but it looks like a 6 inch) Dr performance single stage chip. 35 inch tires everything else is stock. I calculated the MPG's Im getting around 9.7. Now this doesnt sound right. Could the speedo be off? The dude did maint at a Dodge dealership. It has 64k miles. Any ideas? Im new to diesels by the way.

haha ya it could be off but i'm guessing it'd have to be way off but 35's ya i'd say that could be about it but you'd have to be haulin ass when your spedo says 65

I dont feel like im hawling ass at 65 so that makes me think It has been healed, Maybe Ill just get the smarty

no if you're gettin 9.7mpg theres somethin wrong but then again i don't run 35's. do as you wish. but if there's somethin wrong your gonna make it worse

hmmm well, I wonder what a intake and exhaust will do

I have a 2003 5.9 diesel 4x4 with a lift kit and 35 inch tires gear ratio 3:73 milage 17 -20mpg 20 is setting the cruise control at 70 and not bucking any head wind. 9 mpg? you sure you aint leaking fuel some where.

no no we're not talkin an intake and exhaust here. i'm waitin for some to chime in. that is bad.

maybe ill take off the dr performance chip and see what that does

9.7 mpg you would have to have liquid diesel running out of the tial pipe or a tremendous amount of smoke i would think, I would recalculate my MPG again and make sure the Odometer is correct, I have heard of some 14-15 mpg but never 9 but my 2003 is my first diesel and I am still learning myself. lots of upgrades and more to come.

haha haha ya i dont have any experience with that chip but if its shitty that can do it and dont stand on it either! drive normal. is it smokin at all?
