The VVEL system might create more power, but honestly it will be a larger expense, because you will need to incorporate an exhaust cam into the tuning mix to see true benefits.

From my understand, the exhaust cam is already quite aggressive with the Z. I'm sure it can be designed better as any OEM would never make anything too aggressive. But, full control over the intake cam should do wonders. Imagine being able to set your own profile, your own lift, your own duration with the flick of a mouse? Less overlap can already create more boosted power with gains for NA motors as well. Most of what VVEL does has to do with emissions. But, when we have control, that is the icing on the cake.
Also, with the recent exposure to osiris from ecutek, it is quite possible that we are leaving quite a bit on the table. DE and HR motors are making the same power with more boost. Imagine what our motors can do with that same amount. HP per PSI should dramatically increase.
