H&S mini maxx/unlock code

I bought the H&S mini maxx for my truck and install it along with the cold side hard pipe two weeks ago. Me and my buddy were underneath the truck looking at how filter and seeing what needed to be done if I decided to take the filter off. He accidentally grabbed the sensor and bent it. I was heading out of town labor day weekend and noticed my truck started losing power slowly and i could hear a air suction noise, and of course i look underneath it and the sensor is pretty much gone from where he bent it. It was labor day weekend so there is no dealerships open or mechanic shops, so i limped it home about 80 miles and kept the egt's under 1000, cause i had no other choice really. I just bought the unlock code, cause i just don't wanna deal with that filter anymore. I thought it was as easy as putting the code in and using the tuning files that come with the H&S, but from what i read. It seems like you have to get a custom tune too. H&S is closed on the weekends, and i wanna make sure i get this right. Also, does anyone think i may have did damage by driving it like that? The truck was in limp mode basically and i had no boost.

6.4 need unlock codes???

Edit, I see what you are saying. What is your minimaxx part number? You bought the MCC unlock code, and yes you will need custom tunes unless you know how to tune yourself

Do you mean that you bought the MCC tuning unlock code for your tuner? The MCC software allows you to make custom tunes, or pay someone to do it for you, but it's a very complicated program. It wouldn't be impossible for you to tune it yourself, but it's not something I would recommend for someone with no experience tuning engines (myself included).

BTW, I have Gearhead tunes. He's much better at tuning my truck than I am.
