Do you need the juice box with slip ons? I have Akrapovic on mine with no box. Am I running it too lean?
I really asked around about this, as I was told by the guy that sold me the bike that I HAD TO get a power commander if I was going to put on slip-ons.
I learned that they were basically hoping to just make another sale by having my add the PC to the total bill...
100% of the mechanics I spoke with told me that if you get a full system, you MUST get a PC. However, if all you are doing is putting on slip-ons, the PC is not required. They explained that the bike's ECU has to be able to adjust itself slightly for changes in elevation, and that it reads the change in pressure on the exhausts as a slight difference in elevation chage, and it adjusts the map accordingly. They said that if there was anything wrong, the FI light would come on. The bike has 6000 miles on it now, and the FI light hasnt come on, and it runs like a beast. I was told that I would be wasting my money to put on a PC if I wasnt going to also change the air filter and headers.
Thats just what Ive been told. So, I never put a PC on mine.
