Chevy duramax

[snowslut]

I'm running an 09 6.6L duramax with 35 inch m/t's and 6 inch suspension lift. I have an intake , programmer and dpf delete kit on. Was just wondering what other duramax drivers are getting for fuel mileage hauling their sleds .

Pulling a trailer? Or deck?

I usually just use my deck with two sleds

I had the same set up on my 08, lift, delete, 35s. At 110 down hwy 16 I was around 18liter per 100. Any faster and it was way over 20 liters per 100 km

two place trailer, no lift but dpf delete and programmer 14.1l/ 100km

Best I have ever got was 10.5 liter per 100. Empty at 100 km an hour. That's going by the instant economy, not very accurate by any means. Never really did work it out on paper

This weekend I ran 17.1L /100km with two sleds on the deck to vale. From sherwoodpark I could hardly made it on one tank

I hope you are also are taking into consideration that the cetaine rating is totally different from summer to winter and causes the mileage to go down considerably as well as idling a lot more

Another factor is that most power programmers will skew the fuel economy calculation because they alter injector pulsewidth, depending on the power level they are set to. It's more accurate to do the calculation manually. In my experience, he lifted trucks never get the fuel economy that a stock height truck gets.
