Anyone running power boxes on acerts and how are they performing?
Looking to increase performance and fuel mileage on an 06 C-15 acert. Its set at 485 horse right now and been told to turn it up to at least 525 to increase fuel mileage or look at installing a power box. I have Pittsburgh power mufflers and fleet air filters on order to install. What are the benefits of installing a power box over just turning up the engine?
Is this a good question?
