Hi all, im new to this forum and new to snowmobiling and in need of some advice. I just bought a 98 powder special efi LE and am wanting a little more power. I bought some blackmagic twin pipes and can off ebay for 200 bucks and now need some kind of a chip. what chips can I use with these pipes and where can i buy them. appanently they stopped making black magic pipes and having a hard time finding the black magic chip. oh also what clutch kit or setup will be the best for performance, i dont need to go 110 but just want faster acceleration and overall more power and throttle response. i found the 98 powder special has the same engine as the 98 zr 600 so this question is for you guys too, thanks!
