Hissing from hfc, is it a rumor?

Perfect! That makes sense...Do you, or anyone else, happen to have a screenshot of the table that controls VVEL?

VVEL controls are still limited, only certain Uprev Pro tuners have access & then ECUtek claims to control VVEL but you have to go to a tuner (no end user option yet).

HFC really helps bring out some sound life to the Z. So due down pipes of course, if u can stand the smell. But after installing the Berk HFC using Ramps (no room under the car, barley squeeze under it with stock suspension) & doing it all buy my self (FML). Not to mention having a Cat back exhaust on the car already (have to remove the Y pipe on most aftermarket) I can truly say it was a bitch. No question...A whore like no other. But well worth it when you put her in her place and get it done. Glad that **** is done.

Under the $775 option of the Osiris Tuner from UpRev it says that the parameters supported in the ROM editor include "Cam Phasing for equipped vehicles." Wouldn't this be the option that would allow us to tune the VVEL system? If this issue is really harmonics of the engine at that certain rpm then changing the way air flows through it may solve the issue.

Another question, are most of the users on this forum doing the tuning themselves and if so could someone try this or perhaps changing fueling at that rpm and 0% throttle position? That would change the fueling under decel if Im not mistaken.
