2015 kx250f full exhaust question

[Biddi6]

Do I need my ecu mapping to be reprogrammed for my full exhaust system (fmf rct4.1 Complete with mega bomb). It’s a 2015 kx250f and the only “power” mod is the full exhaust. The bike seems to be running flawlessly through the whole rpm range. It has the black map connector in it I believe. Since it’s running fine I think it should be okay?  Thanks!

Have you checked your plug?  That should tell you if you need to change the mapping.  Even if your plug looks good, it might be worth a call to FMF to see if they recommend a mapping change.
