Very good thread indeed, I had to revive it since I am all wondering what the best idea will be for the APV's for my setup, NA Renesis for now but very soon Turbo Charged. Using a Haltech Sprint RE EMS. I can't seem to understand if this Haltech controls the APV's or not at all..

They've been locked open on my engine for the past year 'cause we keep melting the actuator....
And without a locking mechanism they stay where they're put, I tried it before making a pin to hold them just in case.

It makes peak torque at just over 5krpm but obviously the intake/exhaust/fuel system, etc, means it not really comparable to an otherwise stock engine, it makes 90% of that from 3.5k to 7k, even with the ports open.
Tbh, it'd probably be emissions it would upset the most from poor fuel atomisation, however, without some optimisation of the the other port openings and mapping, the initial dyno with them simply locked open all the time on the normal (I.E, valve switchable) mapping did cost almost 30lbft of torque loss down low.
Some dyno work negated most of that from 3.5k upwards, but there's still a loss down low.

What tuning software are you using to change the APV settings?
Ahhh, so I open mine..cause I haz big turbo.
I think I understand what Brettus is getting at now though.
I actually just lowered my APV to 4800 for my run to grab lunch. Its wet out so I was only at a couple psi, but the car was like "LETS GO!" when they opened. Cant wait to try it with full boost. I had actually not touched those settings at all till today.
