Just looking for some input. I have an 08 6.4. I was running it stock with the exception of an AFe stage II intake and getting 13.2 mpg average. I had a local guy cut off the DPF, tune the EGR off, and give me about 60 extra HP. I don't notice the HP gain at all unless I really floor it. I presume he did no fuel tuning as I still have about 3 second of bad lag at dead stop to WOT. I just went with this guy because he was close and I figured the DPF delete and retune was fairly simple. I wish I knew someone better around OKC who I could trust to tell me more a out what I could do to my truck and actually do the work for me.
Anyway, I'm only seeing a little over 1 MPG improvement. I was hoping to at least get it up to 15-16. Thoughts?
Also, what should I do next to this truck for longevity and performance? Thanks all.
Honestly, I would say you didn't research your plan well IMO. A dedicated tuner, intake and exhaust would have gotten you there, with more options than you could probably use... but nice to have. The majority of your fuel savings will come from having removed the regen function and will be realized over tanks...
I gained nearly 100 miles per tank after modding. Then I lost about 60 miles per tank with the lift and tires. Still on the plus side and with way more power...
