Hi mate
I have removed mine, as I use a Blitz Boost Controller, which frankly does a better job! The boost controller uses dual solenoids to control boost, which can be set on either an RPM or Speed calibration (4 target settings). I use mine in a more simple way - set the boost, and it then tries to achieve it.
The Amal valve provides limited boost control to the ECU, but this way, the Boost is regulated by the controller, and the ECU maps to that boost.
I know that you need to be careful, as if you exceed the boost that the car has the fuel and the map to accommodate, then you will make the engine go bang! Remove the amal valve, and you remove one of the ways that the ECU can compensate.
Please correct me anybody if I am wrong!
This is in a 2WD cos

They are getting used less because they are obsolete, There are just better ways of controlling boost eg the blitz controller mentioned above

nothing against other people using it matey,but to me i prefer things simple,for me i want things set up properly ONE way!suspension,or boost,or gears or anything really,this stops me playing about with it and fooking it up!

yeah the temptation is there but im aware of my own limitations!the next big power car i build will be set up by someone else and will be left,until i ask them to do some more to it,i will leave the setting up of that stuff to pros so i can enjoy the driving more!if i play with it ill kill it and never get to drive the dam thing!

why would it be a joke? i hit 2.4 bar using an amal valve. Why would i want to fit a £200 electronic boost controller when its not going to make any difference. Its not going to make my turbo produce any more boost and all it will allow me to do is turn the boost down. I would have the electronic boost controller wide open on max gain so it wont be doing a thing other than allowing max boost.

Most boost controllers work by bleeding air off the actuator, thereby preventing the wastegate from opening. This in effect allows the turbo to create more boost!
Without proper control, the boost would simply continue to rise until the engine or turbo or both went bang.

rich,because as far as im aware it is physically impossible to turn boost below the actuator with a boost controller of ANY kind! 
an amal valve is only a fancy bleed valve,same as a new fangled boost controller,theres just more options and fancy flashing bits.

I set mine to 14psi, and then use the controller to bleed the turbo up to 32psi peak, 28psi sustained

Indeed, but if you have enough pre-load on the actuator on a t34 then it cant make any more boost as its just not capable. Do you think by fitting a blitz boost controller i will make any more boost then using actuator pre-load and a jet in the amal valve. Please tell me how you can pshyiscally overcome the limit of a turbo.
No arguments that if you are achieving the maximum boost that the turbo can make, then the Boost controller wont help you!
But to be fair, I find that my turbo creates quite different levels of boost in different air temps. As such, I find that I can accommodate these in the boost controller much more accurately.
I use mine with a T34 with a 0.63 zorst housing.
I have to say, if you are running 2.4 bar from a T34, then you are running more boost thatn I have with one - at 2.4bar, the controller would be maxing out anyway! At this point I would put my head in the sand and hide!

did have one (still do really) but had a problem with boost so i took the internals out of it and the car boosts fine now...my car has been mapped flat out for the injectors i've got so i have no need for a controller the valve is still in place but i dont get a high/low option

read the above mate,i dont do aftermarket,i was merely commenting on the fact that controllers increase,NOT decrease boost.if you were to remove the amal valve,then add a controller it would INCREASE the boost. i dont see why you would run both! an amal valve and a boost controller do the SAME thing just with different levels of technology etc....so you wouldnt fit BOTH,so if you fitted a boost controller then yes it would increase boost above what you have set on the actuator

Im saying it will only allow me to turn the boost down with the gain control. The point im trying to get accross, is why junk the amal valve when all the electronic one will be doing is set on max gain and wide open. Who said anything about running both lol

right,down from your CURRENT setting,but UP from the base setting! i thought you meant if you fitted it you would only be able to turn it down from base setting! 
my head was ready to explode!

If the answer is yes, then simply, the Boost controller would make more boost (if the hardware can take any more....) If the answer is no, then it wouldnt.

Amal valve was buggered on mine so its got a dawes device fitted now and boosts fine, needs setting up properly though so I only have it set at 16 for now.

with a boost controller, it will compensate for any changes.

always peaked at 34psi (im a boost junky and usually watch the peak! ) never any difference at all that i noticed,certainly never hit any boost cuts etc..
