Not sure if this belongs in the "Marine" area....
You need to provide more details to get a better answer. What is your application, engine rating and current load operation? Fuel consumption at load factors, etc.?
If you dont have CAT ET, I would suggest contacting your local dealer. They can perform the cylinder test and also take ECM histogram at loads and compare load factor, RPM, and fuel settings. What is confusing is that your asking for how to test for low power but your post states "Low Power" in the title? What is your actual complaint and under what circumstances does this occur. Any recent services done?? Major repairs??
My experience with IND products are that people generally operate them in an overloaded situation and have to wait for the turbo to recover or an ancillary attachment. An example would be a tubgrinder...
However with no knowledge of your application my advice would be the following :
1- CAT ET on the unit and review the ECM flashfiles, fuel settings, RPM and anything else the tech may find relevant for your application.
2- install fuel flow meters on the unit while under operation and calculate fuel demand and HP output as simple backup-
3- Contrast the above items with the TMI data ratings from the engine - Have your CAT Dealer do this.
4- Ensure all files are up to date and check for service letters, PIPs/PSP -
5- Check your Intake system - filters and housing, turbos, etc.
6- Check your fuel system for restrictions.
Id probably change your filters first and see what happens- usually restrictions are typically the associated issue for a basic low power complaint. If your application is in severely contaminated area such as a quarry or mine, your scheduled maintenance of filters and such will need to be evaluated to ensure proper operation and reliability of yoru equipment.
Hope this helps,
