Forge Evo Ix Actuator Test
In terms of operational differences between the older diaphragm based units and the new piston based units, they're very similar.
The piston units are slightly smoother in their onset/delivery of boost, but they still use the same springs for adjustability as the diaphragm based units, so there's virtually no difference in the amount of adjustability or boost capacity that either offers.

There is a specific unit used for Evo 8 OEM and OEM-based turbos and a completely separate unit used for Evo 9 OEM and OEM-based turbos.
Essentially, the actuator bodies and internals are the same, but there are different brackets, rods, and turnbuckles used between 8 and 9 turbos. They are not cross-compatible. An 8 unit will NOT work on a 9 turbo and a 9 unit will NOT work on an 8 turbo. We will be offering these new piston based units for all applications, however.
Officially, these units are not yet available to the public as we have been finalizing a few things, but we should be offering them to the masses within the next week or two.
AMS got the VERY first production unit we received from the UK and is dyno testing it.
GSC will be doing the same.
Scott at TTP helped us with some development on these.
Ruben is a local friend and has the first one released to the public.
Stay tuned.
These all-new piston-based units having been a long time coming and will be well worth the long wait!

We will be tossing my car on the dyno this week for a back to back dyno session. With the actuator and without.
My initial impressions are great, the car holds boost very well to redline. I have not had a chance to really beat on it because the new boost curve does require a new tune. I am very anxious to see the new results.

We will be using the new EvoIX piston actuator on the EVOGREEN!
We have 3-4 piston type Evo IX actuators available for sale to the public and one RARE prototype piston "test" actuator for Evo VIII available. If anyone is interested in being one of the first to have these, send me a PM.

Some more photos to drool over:
The red sticker denotes the color and PSI rating of the spring installed in the unit.
Green - 5-10 PSI
Yellow - 10-15 PSI
Blue - 14-18 PSI
Red - 19-24 PSI
We will be pre-assembling ALL units with Red springs. If someone wants a lower rated spring, it will need to be special ordered and it will be assembled specifically for that person.

If you set it up so that your boost level and curve changes dramatically from where it was previously set, then it's very possible that the car will need to be retuned.
If the boost level remains relatively consistent, then it may not be necessary.
That is something that you'll need to discuss and determine with your car's tuner.

I'll go out on a limb and say that if someone already has a flash of some sort that is tuned for or capable of boost levels in the mid 20 PSI rage (ie: boost limit raised, redline raised, fuel-cut removed, etc), then you won't need a complete retune. It MAY be necessary to accomodate for the possible change in the boost curve (meaning quicker spool), however, but I don't know much about tuning, so I'm really not sure. I leave that to the pros.
If someone has a bone stock car and plans to bolt on our actuator (with a higher than stock rated spring) and the boost controller of their choice in an attempt to run 20+ PSI, they're "$h!touttaluck" and will surely need some kind of flash.

Before anyone asks, the dual ports are NOT specific to the Evo applications. They are just shown for illustration purposes.
Dual ports would only be used on an application that requires or can accomodate a dual port boost controller, which most people are not using. We could custom build a unit this way for someone, but the VAST majority of you will never need it.
A retune would be effective in pulling HP out because with this actuator the car will be carrying more boost to redline. So in turn your AFR would be different the the upper RPM range.
put it this way, I am retuning my evo for it
