Help! Sorry in advance for long tread…I own a 2010 ram 2500 Cummins 6.7 bought it with a minimaxx fully deleted 5 years ago. Was working great up until 6 months ago. Wanted to see if changing timing would help fuel mileage on highway so I had to download tuner off the truck. Redownloaded the tuner with timing adjustment & noticed no change but more laggy on bottom end so I downloaded back to tuner put back to default & when I tried to redownload it locked up in “PREPARING TO DOWNLOAD CONFIGURING VEHICLE DO NOT UNPLUG” waited for hours nothing changed. Looked into forums thought it was bad minimaxx. Bought a new one same problem. Looked into more forums found very good chance it could be PCM. Bought one from FLAGSHIP installed it SAME EXACT PROBLEM!! Anyone out there know how to resolve this?? My truck has been in “reduced power” mode for months now. Thanks in advance!
