spartan tuner

[415dad]

can you run the spartan tuner with out putting on the DPF delete pipe? and does anyone make a DPF pipe look like the factory. i live in the California and not sure i want to put the DPF pipe on every two years for a smog check. if the DPF was a factory unit but missing all the insides stuff would that work? a trip to a junk yark and some time???? not sure how much a used on would cost. just looking for better gas milage and engine life...

If you want better mileage you have to delete the dpf. No getting around it.

Spartan does have DPF on tunes though
