I have had the XRT tuner on my early gen. 6.7L Cummins for about a month now, and I just want to say thanks. The truck was a complete disappointment until i installed the XRT tuner. Keep up the good work!!!!

I love my Black Maxx for my 6.4L Powerstroke! It really sets this truck on fire! This thing is awesome, good job guys.

I just purchased a Black Maxx programmer, 5 inch exhaust and an S&B intake from H&S... WOW what a difference for my 2010 Dodge. The only problem now is..... I want more! I am new to the diesel world and I love it. I am looking to having a long and loving relationship with H&S.

I installed an EGR/Cooler Delete, Turbo Back Exhaust, Fuel Rail Plug, and an XRT on my '09 6.7L Cummins. Everything has been installed for about two months now. Only one word to describe H&S products: FLAWLESS.

I installed an XRT, EGR delete and dpf delete on my 2008 dodge 4500 cab and chassis 6.7 diesel. It was easy to install, is working great, and I am very happy.

Thanks for great response! Needed a new mini maxx for my LMM due to screen lock up and a new one was over nighted the same day. Thanks so much for your help.

I've been running one of your first gen 6.7 deletes since they came out. Stepping up to a blackmaxx in a few weeks. Thanks for supporting the 6.7 community!
