[QUOTE="Powerstroke Cowboy, post: 1558742, member: 610"] Ok. I have have a mini maxx as well on my 6.4. But I believe mine is a H&S from back when H&S was still around. Mine has the unlock with the HD300 tunes as well. I believe yours would not. I also have had it for about 7 years. My dad does have a mini maxx bought from the same place you got yours. But it's on a 6.7, just did it, so far so good. First off. Have you contacted minimaxxtuner and let them know what's going on? Something could very well be messed up on there end. Secondly, have you tried returning the pickup to stock. Than redownloading the tuner? [/QUOTE]
