| Dpf Delete And Mpgs!!
To all of you brave souls who deleted your dpf, what kind of mpg improvement are you seeing and any problems? Also I have a magnaflow dpf back kit right now and was wondering if I could just buy turbo back to it and save a little cash? I want to go foward with this but I am extremely nervous about ruining my warranty or hurting the truck so any of your success stories would be apreciated.

| We have reports anywhere from 3-6 MPG gains. It all depends on how you drive really. If you hot rod the truck, your not going to see much. If you jump on the highway and set the cruise at 70, expect some really good gains.

Yes, you can. You can pick up a front pipe only and graft it w/ your current DPF Back.
I avg. around 16 mpg. I can get it to around 20mpg, but I just don't have the discipline to baby it.
