I'm new and i saw a bunch of dif, posts but they flip flop, so do you need a programmer? i was planning on getting an hmf performance slip on or an fmf powercore slip on (which do you prefer) i had an hmf on my 400ex and i loved it compared to stock. When i put it on before i got it jetted i did see a huge power difference so not understanding why i wouldn't w/out a programmer. also i put the 13t on my 400ex, i do alot of trails/hills, i don't race, but i hear alot of ppl talking down on the 13t so give me suggestions for that please. and if anyone knows where you can get directions on how to change that can you point me in that direction as well, it looks like its gonna be a pain compared to the 400.
thanks ahead of time!
