Question 2008 Polaris Sportsman 500 EFI (HO)

Does anyone know how or what to do to the fuel injection system to increase the lower end power? I have installed a new high performance clutch kit, a high performance belt and an aftermarket slip-on exhaust. Now, I hear that I can install a Power Commander to change the fuel/air mixture curve but there is no Power Commander made for this model as of yet. The other upgrades have helped somewhat but I still believe there is more power to be had. Thanks!

You might try gear reduction. There are a couple of companies making them. They go in the transmission but the change top speed quite a bit.
