Edge CTS confusion
 

I'm looking at getting a tuner for my truck 07 Ram CR 5.9 and have been looking at the CTS but am confused. Is this just a gauge monitor unless I get the attitude option? I have read on some places that say it has 3 power settings by itself then others don't mention power setting at all and just gauge functions. Thanks for any info and sorry if this is a dumb question.

The EDGE INSIGHT CS/CTS is the monitor. The others are the programmers. i called thoroughbred diesel the other day and asked the same question.
