I have a 07 raptor 700 that i put a K&N air filter and hmf exhaust on. I did not do my EFI yet because i didnt know which one to use or how they worked. Ive looked all of em up and was just going to go with the HMF fuelcontroller EFI because it matched my exhaust. After extensive reading on this forum (Newbie here) i think a PCV would give me more bang for my buck with my set up. Does anyone know which EFI could be best for my set up and how to map it best?
