A gauge is better then nothing at all, but the real knowledge is the trends that happen in conjunction with and correlated to other actions and measurements.
I have proven beyond a doubt that when people preach they are “draining the rail “that this is erroneous. The screen print below is at the 928 hp tunes on project X this shows that with one Industrial Injection stage II CP3 pump that at this hp setting the rail is still at 26,500 lbs of pressure.
Knowledge is the key to making power; I absolutely believe that if you don’t have a data logger, you are running blind. Can you make power and run good with out one, the answer is yes you can, but you can run much with a data Logger.

$ 588.00
Diesel rpm pick up $ 75.00
Rail pressure interface $ 30.00
Total $ 693.00
This will give you engine rpm, drive shaft rpm, rail pressure, and got 30 additional dollars you can monitor rail pressure out of you pressure box also, this is some interesting info.
Now that a basic system,
Add boost pressure and drive pressure for $ 136 each and. one egt’s for $ 160
Total for that system combined cost of $1118 .70 this is the minimum I would use
For $1895 you get the best of the best with 6 egt’s temps in and out of the intercooler
