Hello everyone, I'm new here. I have an 08 cummins that has been deleted since 2012. I have been using a H&S Mini Maxx with overdrive transmission tuning for my revmax 550 transmission. There MM has recently started acting up and is currently in recover mode from what I believe is a bad SD card. I am unable to find SD card files for ver. 6.7.50. The truck is running fine, but I do have a check engine light and a few codes. I think it's time for a new tuner. Hopefully the MM will let me return the truck to stock, but I don't want to try until I have a new tuner in hand. What is recommended now days? I pretty much quit following tuning once I found a setup I was happy with. I usually run with a mild HP increase (60-80hp) and would like something with trans. tuning. Any suggestions?
