What should duramax injector balance rates be?
GM states that balance rates should be no more than plus or minus 4 (+4/-4) in park at operating temperature. Unfortunately balance rates do not always provide a 100% accurate diagnosis of the injector’s performance due to numerous variables present in the engine.
What can cause bad injector balance rates?
Why is this? A lot of the time, the answer is just plain old worn parts. As the injectors wear out, the high fuel pressure (in excess of 26,000 psi) causes fuel to leak past the worn areas, and more fuel reaches the cylinder than the computer is commanding.
What does a high injector balance rate mean?
The balance rates are relative to each other so if you have a clogged injector or a cylinder with low compression, it will be a high positive rate (ie engine is adding fuel to that cylinder) while the others will typically have negative rates (ie engine is pulling back fuel from those cylinders).
What is balancing rate cylinder?
Balance rate – Is how much each cylinder varies from the average. Measured in mm3/sec. Thus to know the fuel rate for an individual cylinder you must take the fuel rate and add the balance rate. For example if the fuel rate is 9 mm3/sec and the balance rate for cylinder 1 is -2 mm3/sec.
Are there balance rates on a Duramax Diesel?
If you’re big into diesel engines, especially the Duramax diesel engines, like we are, you have probably heard of balance rates. You are likely even familiar with checking them so that you can determine the health of the injectors in your Duramax.

What does a balance rate on a car mean?
Essentially, this is all the balance rate is measuring. When viewing the rates, a cylinder with (+) means that its injector is using more fuel than the average fuel rate and a (-) translates to less fuel. GM states that balance rates should be no more than plus or minus 4 (+4/-4) in park at operating temperature.
