What should be my PID?

I have the 3D.

Which settings are the right ones to use: 
[list type=decimal]
[*]Initial programmed controller settings?
[*]User Guide (page 16) settings?
[*]Smokin-It's OEM?
[/list]

The initial PID that was programmed into my controller:
P = 60
I = 800
D = 150
T = 2s

The documentation/user guide/manual on page 16 has these initial values:
P = 7
I = 600
D = 150
T = 2

Parameters Used in Smokin-It's OEM controller
Model 2
Symbol  Description  Initial       
P  Proportional band  60       
I  Integral constant (second)  850       
d  Derivative constant (second)  130       
Model 3:
Symbol  Description  Initial       
P  Proportional band  60       
I  Integral constant (second)  500       
d  Derivative constant (second)  130

Model 4:
Symbol  Description  Initial       
P  Proportional band  45       
I  Integral constant (second)  875       
d  Derivative constant (second)  220

Thank you.   
 
The correct settings are the factory settings P 60, I 800, D 150.  You can always perform an auto tune if you feel it is necessary or tweak the values to get where you want the controller to go. I have not found a need to do either.
