Anyone had any luck self-tuning (not auto-tuning with the Z-AFM) the Bazzaz Z-Fi to smooth out the fuel delivery and the surging/popping? I have a 2011 Monster 796 w/ K&N air filter, V&H CS One slip-ons, and Bazzaz Z-Fi fuel piggyback and I'm wondering if anyone has successfully adjusted their fuel delivery settings without buying the additional self-tuning Z-AFM module. If yes, any tips/insights? Surging even at steady throttle while cruising is annoying and unnerving in the corners. Thanks.
