The Edge Insight CTS3 is the #1 preferred digital gauge monitor used by daily drivers and enthusiasts. It is hands down the best monitor for Cummins powered trucks. The CTS3 is a great monitor for those who don't want to tune or modify their Cummins or for anyone with performance upgrades looking for a state-of-the-art monitor.

Edge Insight CTS3 monitors are not able to tune your Cummins, so any tuning or tuner devices must be done separately. However, certain tunes like EFI Live (often regarded as one of the best diesel tunes) do not have monitoring capabilities. Other 5.9 and 6.7 Cummins tuners have monitoring capabilities, but often with lackluster displays and gauges.

Enter the 3rd generation Edge Insight CTS3. This monitor offers a 5", full-color, capacitive touch screen with auto-dimming. The gauges and backgrounds are highly customizable and there's even an accessory system to control switches for lighting, winches, compressors, etc. Cummins Edge Insight monitors also offer built in performance meters to measure 0-60, 1/8 mile, 1/4 mile times, and more.

Cummins Edge Insight CTS3 Features

  • 5" full-color touchscreen w/ auto-dimming
  • Monitor key parameters like EGT, regen, trans temp, boost, & dozens more
  • Built in performance measures 0-60, 1/4 mile times, and more
  • Highly customizable gauges & backgrounds
  • Swipe between screens with different gauge displays
  • Advanced data logger with export capability
  • Read and clear DTC codes
  • Simple OBDII plug and play installation
  • Includes windshield mounting bracket

The 5.9L and 6.7L Cummins Edge Insight CTS3 is compatible with any tuners as long as the OBDII port is free. Its 5" full-color touchscreen and easy navigation make for an excellent monitor. Track dozens and dozens of key parameters and easily swipe between screens with highly customizable gauges and backgrounds.

Insight CTS3 devices also feature an advanced data logger with easy export capability and the ability to read and clear DTC codes. Simply plug the CTS3 into your OBDII port, mount it to your windshield with the included bracket, and enjoy the benefits of the best Cummins monitor on the market.

Cummins Insight CTS3 Customization

  • Hundreds of combinations of gauges in digital or analog format
  • Set audible and/or visual alerts if certain parameters are met (i.e EGT too high, AFR's out of range, etc.)
  • Expandable Accessory System (EAS) compatible for additional sensors, switches, lighting, and more
  • Supports backup camera installation and displays on Insight CTS3 monitor
  • Adjust background screen, arcs, needles, colors, and more

Ultimately, the Cummins Edge Insight CTS3 offers too much customization to summarize in words. If you're looking for a Ram Cummins monitor and datalogger with excellent features and customization then look no further.

Why should I buy the Insight CTS3 instead of a tuner/monitor combo?

The Cummins Edge Insight CTS3 is designed to be a monitor and datalogging device. That is the primary goal of the CTS3 and it does it at a very high level. Most tuner and monitor combos put tuning first and have less emphasis on monitoring and customization. This monitor certainly isn't for everyone. If you don't want a high-quality monitor and logger or you're just looking for a tuner to set it and forget it then the Insight CTS3 might not be for you. However, if you're looking for an advanced monitor then the CTS3 offers customization, features, and gauges that are superior to tuner + monitor combos.

Why don't you offer the Edge Evolution CTS3?

Edge Evolution CTS3 devices offer the same monitor, logging, and customization as the Insight CTS3 but also act as tuners. However, at Boosted Performance, we try to offer the best of the best. The Evolution tuners aren't known to be the best tuning options around for the 5.9 or 6.7 Cummins. MADS, Bullydog, and EFI Live are some of the best tuners for the Cummins so we only offer those tuners.

Does the Cummins Insight CTS3 work as a tuner?
No, the CTS3 is simply a monitor and does not support tuning. However, the Edge Insight CTS3 is compatible with tuners as long as the OBDII port remains free.

How does the CTS3 work with tuners?
Most tuners will require temporary use of the OBDII port to flash the tune to the engine control unit. Once flashed, the OBDII connection can be removed and the CTS3 is then simply plugged into the OBDII port. The Edge Insight CTS3 is simply a monitor and datalogger, so it will not interfere with or change the tune.

Why doesn't this ship to California?
The Cummins Insight CTS3 is CARB-compliant and legal for use in all 50 states (since it does not change any emissions or performance and simply reads parameters). However, most products we offer are not CARB-compliant so we don't currently ship to California.
