i just got done doing an overhaul on my f4i, plugs, filter programmer etc. i have a ixil exhaust not one readily available for a map download from powercommander lol. so i emailed them and they told me the closest thing would be the jardine rt-1 map. i am currently running that map but i have lost some low and midrange. "gained some serious top end tho". i was looking at the map and through the rev-range, its pulling what seems to me quite a bit of fuel out of the motor during that portion. for the jardine exhaust im sure its correct but mine not so much. do you guys think that i sould just put a little more fuel back into my bike throughout that range and if so how much? i thouht about starting with just going by increments of 2 on everything and use that for a starting point.

 

i say go for it, let us know your resaults.

 

Well added the fuel through the rev range and it helped, less popping on decel and gained some of the midrange back. Still could use a litte more tuning but idk if I'll mess with it lol... Lesson learned is buy an exhaust that has maps available lol
