YOUR #1 SOURCE FOR #2 POWER!!

Having a good set of gauges is one of the most critical items that an owner of any turbo diesel should have, and your 2010 Dodge Cummins 6.7L is no exception.  Whether you're towing a stock trailer or racing down the quarter mile, having the ability to monitor vital engine statistics is extremely crucial.  We highly recommend the DiPricol Optix and Isspro EV2 series of gauges, its what we use on our own trucks, and that's why we've chosen to offer the two for our gauge packages.  No matter what, you can never have too many gauges, but at least get the basics, so read through, and hopefully you will have a better understanding of what you may need after doing so.

On all diesel trucks, having the ability to monitor exhaust gas temperature is critical, even stock to mild trucks have the ability to create immense amounts of heat when under load, so being able to keep an eye on things can give the driver peace of mind, and hopefully avoid costly repairs down the road.  This is especially true with the 6.7L Cummins.  When this engine goes through a regeneration cycle (emissions process of burning soot in exhaust), it uses post-combustin injection, thus causing the exhaust to get EXTREMELY hot.  Having a pyrometer installed will allow the driver to see when the truck is running this cycle.  All pyrometer (EGT) gauges come complete with gauge, wiring, and thermocouple for drilling into the exhaust stream.  For owners of automatic transmission trucks, having a gauge to properly monitor oil temperature is a great idea.  If you truly use your truck (or abuse it), watching transmission oil temperature will help to avoid the possibility of a complete transmission failure.  The reason for this is as the torque converter can't keep up with hard use, it is not able to properly displace the oil to cool the rest of the transmission, and the end result is burnt up clutches, malfunction of valve body, etc.  We highly recommend purchasing one of our full sweep transmission temperature gauges, as opposed to a half sweep.  Using a full sweep allows the driver to get a more accurate and quicker reading on the oil temperature.

Another very important gauge is a fuel pressure gauge.  Fuel pressure gauges come in two main fashions:  mechanical or electronic.  Mechanical fuel pressure gauges use a diaphragm type of sending unit in which fuel is delivered to the bottom of the diaphragm, and radiator fluid is used from the top of the diaphragm to the gauge.  The reason for this is to avoid having fuel come to the inside of the cab.  An electronic fuel pressure gauge uses an electronic fuel pressure isolator, thus not requiring ANY type of fluid to come into the cab. 

Finally, one of the last popular gauge options for your 6.7L Cummins is the addition of a boost gauge.  What is boost?  Boost exactly is a reading of your intake manifold pressure measured in pounds per square inch.  Basically, it monitors how much air flow your turbo is producing, showing you kind of the "power band" of the truck.  In the past, one had to remove their intake manifold and drill and tap it in order to monitor boost.  However, we can make this task much easier on the installer with the purchase of a boost bolt.  This handy little inexpensive device allows you to simply remove one of the factory bolts next to the valve cover on the drivers side, and insert this boost bolt to draw air from for a reading on the gauge.

Now that you have all of these gauges, where are you going to put all of them?  Fortunately, we offer many options for mounting, such as the popular A-pillar mount, dash top, steering column, overhead (above rear view mirror), and several other styles.  No matter where you put them, just make sure that you have them to possibly save you thousands in the long run.  And if you are having trouble determining what gauges you need, call or e-mail us, we'd be happy to steer you in the right direction.
