There is a difference in PAR Dynamometers tests…the difference is in the TECHNICIAN!  We ensure your Western States’ Cat Engine Technician is Caterpillar certified to perform a PAR dyno test and also interpret the maintenance issues correctly.  A PAR dyno test checks everything from torque to fuel consumption, but interpreting the data and repairing it correctly requires a well-trained, experienced technician.  Western States has them!  They will make sure your engine is operating at peak performance and output.  Dynamometers allow engines to be power and performance checked in the shop before going back onto the highway.  Experienced Technicians allow you to maximize your Cat truck engine performance and minimize your maintenance expense.
