What is the proper voltage setting at idle ??
It should be somewhere between 12 and 14 volts. The more options, like lights,A/C, brake lights ect. that you turn on the reading will change. But it should stay between 12-14 volts.
I hope this helps .
Engine chugging the cutting out
Hard to say, it could be a dirty injector to and bad fuel pressure relay or the vacuume line to the fuel pressure relay. After that you could change the fuel filter, it may be dirty and causeing your pump pressure to drop when on demand. good luck and hope this helps

I have an '08 2500
The 08 diesel vehicles have a particulate filter much like a catalytic converter an a gas engine, these exhaust cannot be modified by removing the filter . The PCM will monitor this function and alert you with a service engine light if an issue is detected . Removing this filter will also cause the vehicle to go into a low power mode until the problem is repaired . It is also illegal to remove this filter as it part of your emission system for that vehicle . I don't think your programmer and intake would cause you any issues.
