by the way i have seen better than 1 to 2 gain as well. i went to idaho without it and never saw netter than 16 on the freeway, i averaged 20.5 last trip. 2 weeks ago i went to san diego, last time without it i averaged 18 going and 16 coming home, with it i was at 23.5 going and around 21.5 coming home. that is at 70 mph. there are other tuners that give you power with the dpf, spartan has dpf friendly tunes as well but i disagree that you'll only see 1 or 2 in gains with the dpf. i don't know anything about the sct, which is the other dpf delete tuner, because i never have had one but i think they get about the same milage out of them. the majority od the cost of the spartan tuner is due to the dash daq. it is a good piece. in my opinion you get way more for the 1000 or so dollars. you can see the demo of the dash daq at drewtech.com.
the 1500 is well worth it in my opinion.
and yes his gains were significant, i used to get 9 miles to the gallon pulling 7000 lbs. thats a 6 to 7 gain. that tuner will pay for itself in a year at that rate
