    Free airbox mod and MNNTHBX exhaust are my only mods.
    What would be a quick fix for this? PCX 150 injector? Colder plug?
    I'm sure its fine. Injector would flood your bike.

    I see all these people checking and worrying about their plugs and such. I ran an exhaust and airbox mod with no tuner with no ill effects. It wasn't until I got the cam did I add the tuner.

    Injector will not flood your bike. It will run very rich for about the first 10 miles of riding and the grom will lean itself out. The stock ECU does a good job of reaching its desired value. Just throw an efie on it to trick the ecu to run a lil richer and call it good.
