Need help on this issue.....Put new (used) header pipe w/o cat on 2010 Ultra Limited with Power Commander V....... lot less heat, better throttle response, etc.......but gas milage is terrible......(30 mpg maybe ?????) maybe less.......Need suggestion please....Thanks a bunch.....This form is great !!!!

 

With less heat, better response and power will lose some fuel mileage although 30 MPG seems pretty low, try easing up on the Throttle a little and check your Plugs for running too rich ..

 

What map for the PCV did you use? Do you have an autotune?

 

Fuel management systems enrich the fuel/air ratio. You're getting the best of both worlds with a bit more performance, allowing the engine to run cooler than the stock configuration. Unfortunately, you have to give up some fuel mileage. How much depends on which system you select.

With the installation of a Ridemaxx fuel management tuner on my '09, the mileage went from 46/47 down to 40/41 mpg.
