Hi everyone. Just got my 09 Duramax (2500HD EC 4x4 SLT) and want to see what popular opnion is on mods for better economy. I do not want to give up any power and a small increase would be OK. I am in a situation where removing the DPF may not be possible so I'd like to hear about mods that will work with it as well.

 

On my FIL's 2006, I added a BullyDog programmer, exhaust, intake and filter. It did not do much for MPGs but it sure helped MPH! :) Well, it did bring back the mileage lost with the bigger tires. I like the idea of on the fly program changes with is not possible with the BD I used. I've used Banks before on a gasser years ago and was VERY happy so I'm looking at going back there. What do you think about the Economind? What other parts would make a difference on the LMM?

 

Thanks in advance.
