    You would be better off getting a Hydro Tec 3L Tuner than cutting your can. Gave my R&D 250 XS a 17hp gain. Popit diverter is a good thing, I assume it's a Simon one?

    Yes it is a simon diverter. Do I have to do the diverter if I change the tuner?

    I have Eric's Poppet Mod. I also have the stock can that is cut. Eric told me this was the better way to go at the time. I don't know what extra I got from the mod, I only know my motor runs like a scalded dog

    I don't know much about motors except gas oil and throttle so I can't answer wether or not this is what you need. Here is a link to the mod though http://www.simonmotorsports.com/poppet/poppet.html
