The 2007.5 and newer GM Duramax, and Dodge Ram 6.7 Cummins
do not have EGT sensors placed pre-turbo where the optimum read-
ings can be achieved. When items such as turbos, catalysts, NOX
lters, and particulate traps are introduced, temperatures can vary
in large margins due to the thermal energy stored/transferred by
these devices. This creates an environment that doesn’t represent
combustion-chamber temperatures as eectively as a manifold/
pre-turbo placed sensor.
Edge Products recommends using a pre-turbo EGT sensor if you use
the CS/CTS for any kind of competition, or heavy hauling. If your
vehicle is not equipped with a pre-turbo EGT sensor, Edge recom-
mends you purchase an Edge Products sensor and install it in a
pre-turbo location.
As noted in the accessories section, you can purchase an Edge
Products EGT sensor to be coupled with the Edge Accessories System
(EAS) or you can purchase a standalone Edge EGT sensor. Either of
these Items can be purchased at www.edgeproducts.com or at
your local Edge Products Authorized MVP Dealer.
If you are unsure whether or not your vehicle is equipped with a pre-
turbo EGT sensor please see the diagram on the following page.
If you are unsure how hot is acceptable on your EGT’s we recom-
mend you do the following:
1 - Display EGTs on your main display screen
2- Observe what the EGTs are in your vehicle while it is at a stock
power level and accelerating at a heavy load, i.e. pulling a heavy
trailer up a long hill.
3- Add 100 degrees F to the highest stock reading you’ve seen and
use that number as your ma x safe EGT.
4 - Record these readings for later reference.
