General query for diesel owners. Mine is an 03 GMC crewcab 2WD shortwide with the Duramax with 38,000mi. The onboard system says i'm getting 16-17 around town and 17.6 on the hiway at about 80-83mph. I'm looking for experiences on mods to help mpg and low end pep. It sounds like an air intake system, exhaust and low hp chip will yield the best results per $ spent. Please tell me about your experiences.
