fuel mileage without DPF

This is a question to the guy who took off his dpf and installed a programmer. What kind of mileage changes did you see?
I was not going to mod this new truck like I did my old ones, but I may to get my power and mileage back.

In one thread he stated he got about 22 mpg. Which is awesome for a duallie

This mod is awesome from what i hear but be aware that when you pull your DPF with the way the warranty is written it is null and void

22 to 23 mpg?! What? That is great for a duallie. I have a single rear wheel that is only getting around 13mpg and no power compared to my old truck. The fuel savings alone would be enough for me to scrap the warranty. I willing to gamble a little bit. I never took my old trucks in for any kind of service. Had 2 7.3's and 2 6.0's. Point me in the right direction please

Thanks for the website address. I saved it and will try to call shortly. I see that you gutted your dpf, was there a big change in exhaust noise? How many miles have you been running the programmer? Any problems? Are you the only one here that has done this?
Sorry for all the questions. I'm excited

There have been others, but I'm the only one on this site that has done it. There is a huge change in sound, its not as loud as a 6.0 but there is more turbo noise....but I've got a couple ideas on how to make it louder.....I have got over 7,000 miles on the old tune and only couple hundred on this new one....no problems, the truck has been flawless!

I bought an 08 twin turbo in April of last year and there is around 20000 miles on it but I'm still getting terrible fuel mileage(13-14MPG) and i was wondering if there was a way to increase the fuel mileage without voiding the warranty?
