******WARNING************
Those of you out there that plan on running the Power Commander should note that the only available maps
are all zero (or no map) and ALL STOCK EXHAUST/ALL STOCK AIR FILTER.
**********DO NOT RUN THE ALL STOCK EXHAUST/ALL STOCK AIR FILTER MAP with the HMF slip on************

The map (M128-001) WILL NOT PROVIDE AN ADEQUATE AIR FUEL RATIO when running an HMF slip on. You WILL run the risk of extremely high internal exhaust temperatures which WILL burn out the packing in the muffler.
MUFFLER FAILURES OF THIS TYPE ARE NOT WARRANTABLE.
You WILL need to have a "custom" map made to run an HMF exhaust with a Power Commander.

The HMF OPTIMIZER is fully mapped on our dyno to our exhaust.
The HMF OPTIMIZER is pre loaded with the best map for basic sea level and 60 degrees.
The HMF OPTIMIZER IS fully adjustable for your ambient conditions and modifications.


****IF you have any problems in set up or tuning ALWAYS TURN THE KEY SWITCH OFF, this will kill power to the controller.

Rancher 420 Horsepower gains.

Because of the lean condition when adding the HMF Slip On we strongly suggest you use the HMF Optimizer.
This will aid in adding more fuel which will keep internal exhaust temperatures at safe levels.
The HMF OPtimizer is a MUST in regions where ambient temperatures drop below 45 degrees.

Failures of the HMF Slip On due to heat will NOT be covered under warranty if the HMF Optimizer is not used.
Basic burshed aluminum Slip On: $239.95.
HMF Optimizer: $249.95.
Available: The week of October 15th.
HMF utility series slip on.
HMF Optimizer. Which IS pre programmed for the best map that we found on our dyno to our pipe @ basic sea level 60 degrees. It IS also adjustable.
Airbox lid off.
For a machine that only makes 16HP all stock a 1 ~1.5HP gain is average.
We tested with a stock type air filter, once a free flowing filter is added expect ANOTHER 1~1.5 more horsepower on top of what we got. So 3HP isn't a bad gain .
There is enough adjustability in the HMF Optimizer when you do add a free flowing air filter, we took that into consideration.
