I like the bass too, but I never have found a good config where I can use the dynamic sound. I usually stick to playback gain to moderate, equalizer on acoustic, and convover with something... Currently running the DBX 160SL Blue - High ratio ir. It is included in the package of IR's you can download in the main viper thread. I have recently started using cure tech but nothing else other than above. You could try enable viper clarity and select xhifi. That works pretty good too.
