Like the title says I've been seeing a lot people posting about how the h&s tuners are what's killing these 6.4 trucks. Obviously like most people i take most opinions lightly. I figured this is more of the I have the option to run a hd300 tune and tow 10k, drag race and get mad when it breaks. What do you guys think? I have a hard time believing the tuning itself is bad. Also what are guys running for low boost fueling? how much can it affect egts towing if at all? what do you guys recommend?
