Hey, fellas, I have a 16 RAM currently running an MM3.
I have 245k on the clock and have been recently having issues.
First if I leave my tuner plugged in, it drains the batteries overnight.
I have load-tested them and have no issues there.
Second, sometimes the screen won’t come on, and I get the red indicator light on the MM3 monitor flashing.
If I unplug it and plug it back in, it will work.
Now, I’m having VGT issues. It started small as the VGT wouldn’t close on the warmup, but after driving 10-15 mins, it gets full functionality.
Now I’m not getting anything.
No VGT at all.
Do I need new tunes/tuner/turbo?
