Is the Z NOT a tuner friendly car?

If the Z was factory FI, that would be SWEET! Tell them to ditch the VVEL too.

The VVEL system will be the way modern cars go, it is early so there are some kinks (think direct injection) but having the ability to electronically control the intake cam is huge. Can easily just dial in your needs with a tune without having to swap out parts.

Dreamer, if what Ecutek is saying is true, i'll be the first in line to jump on their bandwagon. VVEL is a fantastic technology, but only when you can manipulate it. Otherwise we are just throwing boost out of the motor. Literally.

How do you know that though? The VVEL system with a factory exhaust cam plus tuning the intake cam could be worthless. Looking at a lot, and I mean a lot, of boosted VQ37 motors and comparing them across the board to the VQ35 (DE to HR) we are seeing equal if not better gains when applying forced induction.
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.
