Hey guys I just bought a new super duty with the 6.4 I have been reading up on the tuners and would like some input from people who already have them. I have heard that SCT and Scorpion are the best but I have heard some good things about the Black Maxx as well.......so anybody that has gone through this already help me out please. I want to get a new exhaust from the turbo back as well I am thinking 5"?

 

blackmaxx is more generic than SCT, as in PPE vs Efi Live for the duramax, either way i don't think you're going to go wrong also the H&S Blackmaxx already has all the gauges you could want built in, less out of pocket money in the long run
