That thread that was mentioned was my own fault for the way I worded it all because I was pissed off at the time................after it all died down I basically stopped promotion/production. BTW, the other company mentioned did NOT have a dual stage in the first place.

The Dual Stage boost controller we have, I have only built 3 of them to date as they are not on our site or advertised. Mostly from laziness I guess. My RS runs it but I only use one boost controller on it, the other side of the dual stage is wastegate pressure only. So I run 40 on (high) C16 and about 25-26 on low. The other two I built for customers us two of our inline boost controllers so the low and high are adjustable. Works much better like that than the way I have mine.

The problem with some of the other dual stage controllers I have run is the low is too low and the high won't go high enough. It's the same with some of the other standard single manual controllers that are out now, some come with multiple springs but the light springs are to light and then the heavy spring is too heavy to turn the boost down low enough.

With the ceramic ball we are using and this special stainless steel spring you can run as low as wastegate pressure (+2-3 psi) and the high will go higher than we've even attempted to run any car with ease (50+psi).

Thanks for the post Pete. Glad you got the car and you're impressed on the pump gas!

what david is saying about other dual stage boost controllers is true, i have the turbo xs and the high boost would not go above 27psi for me but the low boost did not have a problem being turned up, which is why i got the buschur dual stage as well.

A boost controller that "can't go up high enough"... is normally caused by not enough wastegate spring pressure. What type of springs on your wastegate?

i have a halman manuel that will not go past 25 for some reason & i have a 44m external waste gate i know that should handle at least 40 i dont think the wastegate is the problem at least i would hope not

I had the Hallman also it did work good,the only problem I had was trying to guess how many times to turn it to get to the correct boost level.It was really a pain after a while.
With this new controller it's a no brainer switch off low boost switch up high boost.

It's not the size of the gate, it's the type of springs inside. What spring setup are you running in the gate? The Tial gates can take up to two springs and each spring has a specific PSI rating. As a rule of thumb if you want to boost X, then you need X/2 psi of spring.

IE boost 30 psi get 15 psi of spring in ur gate.

crcain, I do not agree. Most of the time if the boost won't go high enough it is a problem other than the wastegate spring.

The boost controllers are available NOW. I have all the parts on my desk, I just have to assemble each one. Wait.......on second thought, I think we ran out of our inline boost controllers, I bet that's why Nick said a few weeks. I think our second run of controllers are being anodized.

I have to figure out pricing. They are not cheap. The inline controllers are $95 each and the solenoid I had built is from Parker Aerospace. So it's very-very high quality and they were expensive. I also had laser cut brackets made for mounting it. This is the only boost controller built specially for the EVO and mounts correctly.

Let me do a search, I'll see if I can find the picture of it on my car.

OK, here's the thread with a nice picture of the actual inline controller:

Our dual stage uses TWO of these.

Crap, the picture of it on my car is the prototype that is not black and only has one controller.

Pete, can you please take a picture of yours?
