best tuner for 6.7 cummins
#14
I took my truck in for an inspection of the steering control arm on a warranty notice. The guy saw that I had put a Mag-Hytec tranny pan on the rig and he proceeded to lecture me in the parking lot about how this type of modification had now voided my warranty and my truck would now be red flagged and I would be getting a notice in the mail. So at 34k miles I did the mods and put on an H&S black maxx and didn't look back. I have saved enough in fuel to pay for the mods. And the dealer

The true best tuner is EFI LIVE V2 with data logging for a true tune customized to your specific pickup. That is the best hands down.
As far as universal tuners H&S or Smarty get my votes.

Not to bark but... not true Matty, I have a 2012 cummins and am running the Smarty Jr. that Marco loaded the software for and at the dealer they noticed the foot print!!! I am now doing the deletes as I have been flagged and my truck only has 10k miles...
