Slow you might want to give Sam a call and discuss with him the options and maybe throw some ideas around. *hint hint* Sam knows wayyyy more than anyone else in the aftermarket about the VVEL system and may be able to shed some light on how he can tune the system... I cannot say for sure if he has cracked the system or not but from all the evidence that I have seen and heard
I would put money on Sam knowing how to tune VVEL
