I'm going to buy a fuel management system after reading the threads on difference of all systems i have decided that all I need is a cobra but I looked on dlp and they have two different ones and only about 30 bucks difference. any suggestions on which to get. it doesn't have much description of difference other than plug in's on one. can anyone help. all i have on bike now is scorpion tip exhaust and a TRE as far as performance goes but thinking about getting some ducks covers in near future. also i am having low speed surges like many have talked about.
