Ratsbud211 found it was best to use the OEM 9 WGA and let it spike real high and taper off naturally out the top so you weren't just blowing hot air..
Mine is spiking to about 28 and holding around 22 out the top. I feel like I could get a lot more torque out of the bottom end if I went to 30-31psi and tapered to the 22psi but I have some weird fueling issue or something that I need to fix first.

I was at 28psi tapering to 21. My original WGA couldn't cut it. It did have 100k miles on it. Maybe a newer one would do better, but for how long? I'm 100% about only upgrading parts when I need to. My car is as Stock as possible. Unless you ever plan on running less than 18 PSI, there is no way I would stay with the stock actuator.

What kind of torque are you guys getting out of it? I was only able to squeeze 380ish I think was the highest and that had a little knock I think.
One thing that I haven't installed that should help my power is the muse dump pipe, waiting on my new injectors for that. We pushed it up to 30+ psi but didn't make any more power and that is the only thing left that some of you guys have that I don't. Well I guess that and a wga.
I may port the exhaust housing as well and try to get it to flow into the downpipe better.
Another weird thing I've noticed. Around 4500 to 5k Rpm I'll have this little burp of power. It's like it just quits skips a whole rotation of fuel and spark then picks up again. It's not registering as knock, afr don't go crazy, it's almost like spark blow out but I gapped them from. 026 down to. 022 and it made no difference.
It puts a big spike in the virtual Dyno graph too.
It only did this with the larger injectors in, since I put the stockers back I haven't had that issue but it's also turned down some. Only making about 380hp at the moment.
