Busa Back Firing

[AftaMaf]

Can anyone help with this?

I have an 09 Busa with a Brocks Alienhead full system with the Power V commander. I having serious back firing from the system, I was reading about the Air Box Lid procedure or the Marble procedure. Does either one of them fix the problem?

The marble or a tee works too

+1 i just did the marble mod 2 weeks ago and definitely stops the backfiring.
