Fairly certain this is an intake pop, but I can't say I've ever experienced it before so I'm here.

When decelerating and shifting from 3rd to 2nd either blipping or not blipping I get a bang of various loudness from underneath the seat, so much so that I can feel it.
One time it happened so violently that I thought I might have blew something in the motor.

I've heard that this can be solved with a tune? I have the cable, just need the tune for this bike and I'm pretty savvy so I can figure out TuneECU.

Thanks!

Edit: Stock intake and stock exhaust.
 
not smart to put a tune on a stock exhaust system the extra fuel is bad for the cat.
you can however raise the max rpm and open up the throttle plates w/o worry.
it should not be banging with stock exhaust.
if it is out the intake you have problems with the hoses from the throttle bodies.
