So looking at a 2008 or a 2009 GMC/Chev 2500 HD. (note-I did not say I was looking at)

In order to get good mileage and fuel economy what would you suggest for mods. No racing, no sled pulling, no extra curricular activities just small trailer pulling.

What would you recommend and what approx. will it cost?

 

Modded Intake - Freebie

Many of our vendors have the DPF Delete exhaust and small tuners for around $600.

Something I would definately invest in is a Transgo Jr. Shift kit.. they should come stock in all Allison Transmissions. You can usually get them shipped to your door for under $120.
