M4 Exhaust W/O Baffle tuning?


Recommended Posts


Hey guys, i just installed a M4 slip on exhaust on my 2017 FZ-07.  At the same time I also installed a FT ECU data link harness onto my ECU.  Been searching for fuel maps for this set up and can only find some that do not specify if the baffle is in or out.  Does it matter?  I would assume that it does as the air flow is going to be significantly increased without the baffle.  If i choose a fuel map for the M4 and i take the baffle out, how would i know if i need to adjust? and how do i go about adjusting.  would a dyno custom map be the only way around this?
