12 6.7 & 03 6.0
Member
this is my first post so bear with me, I have a 2012 6.7 that is deleted and has been running h&s box tuning for 30k. My questions is to those who have ran custom tunes from spe, gearhead etc what issues, if any, have came up and is it worth going to custom tunes from stock h&s. I don't race truck or tow large loads. mainly a daily driver that I enjoy playing a bit with.
I just had custom tunes on my 03 6.0 and it made a world of difference. Any experience would be appreciated
