My dad just picked up an 07 QCLB 6 speed, 4x4. 6.7L. I have done some reading and it appears that due to the government crackdown, no new tuners are being sold with the capability to disable the DPF after it has been 'deleted.' EGR deletion is still no problem from what I've seen. EFI Live and the Smarty or Smarty Jr. seem to be the most popular options from what I've seen on the Cummins sites. I know a guy running the H&S mini maxx on the exact same truck except shortbed and automatic trans. But I saw that thread on here about them not doing the delete tuning anymore. Also, I know he is not going to want to run a straight pipe. What are some good hi-flow mufflers out there?
