Guys. I'm so ready to get this dpf hunk of metal off my truck. Regin cost 1 mpg. I'm tired of it. I'm in the market for a tuner for my 2012 with 47k. I plan on doing an egr delete exhaust and s&b in take. I'm scared to buy h&s because I'm subscribed to their forum and about a couple of weeks ago it sounded like business was gonna close. Spartan looks awesome but it seems to lack little things like speedo correct but seems to have the most powerful tune. Now sct it looks like a good bang for ur buck but can I get custom tunes from say like punch it like on an h&s tuner. I want my truck to be fast but get good mpgs when I want them. Just let me know what y'all run and how u like it. Thanks
