Hello I have a 10 6.4 and want to do a doc/*** del. I have read that the best tuners are the *******s and the h&s mini maxx for the 6.4. I know the *******s is out of my price range so should a person purchase a h&s mini maxx. I have heard h&s performance is out of business or they don't deal with public anymore. But diesel shops say they support the tuners. Should I buy one there about half price of *******s. Does anyone have any suggestions or other tuners they would recommend thanks
