OP, I have an 08 dmax, my suggestion to add/repeat to the ones already made, pls try them out and update us on the improvements from each.
1. Tire pressure - max sidewall or your confort leve.
2. Cetane addy - TDR-S, sold in 5 gallon buckets from IN, or use Powerservice from wally's
3. Front Grill block - partial or full depending on outside temps - be VERY careful not to burn your cummins pls.
4. Front Skirt/air damp - like a body kit to push more air out and prevent it from going under the truck, I remember reading that 25% of all drag loss occurs due to lack of aero under the truck/car.
5. Aero topper for Bed - this is in my wish list someday when I have time, but search this forum and quite a few innovative products are there.
6. Programmer - WARNING might void warranty, research and look for cost effective solution, might not make sense to spend $1k to save $200
slowing down the best solution, and then a diesel addy in bulk to keep your per mile cost low.
