Hi, I'm also a new Raptor 700 owner, just got one on trade and I love it!
From my research, you have to have an aftermarket fuel controller to tune the bike such as the Power Commander 3 or 5, dobeck, ect... The PC 5 is best I think, you can add an auto tune module to it, it comes with the module and an O2 sensor to take readings and adjusts as needed. The PC3 is next because there are so many maps for it. I'm not sure if the PC5 takes PC3 maps but if it does it would probably be an even better bet because the PC3 needs a 9volt power adapter for tuning while the PC5 does not.
They say the stock ECU will not adjust to anything, but I don't think that's true... It has to at least adjust for altitude, and as long as you aren't in an extreme low altitude it should be able to give more fuel for at least small adjustments, such as airbox lid off and baffle out. I have been running baffle out since the night I got it with no problems.
