Just wondering if the speedwerx pipe and head work on the EFI's. They claim a 9hp increase with the pipe. Wouldn't the fuel map have to be changed for this? I know you can't chip the 2002's so how does this work? Black Magic expresses on their website that anyone selling pipes for EFI units is probably selling you a stock pipe in disguise http://www.snowmobileworld.com/forums/iB_html/non-cgi/emoticons/mad.gif If anyone has tried this setup or has any info let me know, it would be much appreciated. I'm kinda baffled about this. http://www.snowmobileworld.com/forums/iB_html/non-cgi/emoticons/wow.gif
