a friend of mine has a honda 420 guess it would be a rancher or somethin on that line but he has bought an hmf exhaust and an hmf optomizer prettymuch a power commander but has anyone ever tried to tune one with this setup before it comes with no instructions so we have been playing around with it for a few days but it still hasn't gotten any better anyone have any tips or a link to a site with tuning details?

 

Google hmf forum. they have instructions with pics.
