Hey peoples... i was just wondering what you all thought would be better between a dual stage boost controller (bleeder) and electronic controller, and why. I'm actually thinkin' about going a dual stage so i can drive around on standard boost then when i want to go a bit quicker put it on high boost... what do you all think.
well scotty, if you go the electronic way..you can chose whatever you want to run whenever... it electronically sets it to whatever you like, with the dual boost, your basically limiting yourself to 2 different settings..

can you guys also tell me what piggy back computer would be best for my car setup... at the moment i have changed my twin turbo motor to single, but i am going to put new injectors and fuel pump in after i get a piggy back computer. Also i am thinking for the injectors just 550cc supra ones but am unsure whether to get an in tank pump or not... Any suggestions... Thanks in advance

For 550cc injectors, use a bosch 040 in-tank pump.
Go electronic. You may get 2 'stages' of boost with the dual stage bleed valve, but like most bleed valves it will not hold boost effectively.
Having said that, I am running a cheap bleed valve, and it holds boost ok, but definately doesn't work as well as the good electronic units. You also can't control gain or other functions that come with EBC's...
I will be replacing my bleed valve with a Blitz Dual-SBC Spec R shortly.

One thing to consider is that you may be able to change boost to whatever level you want but will it be tuned for it?
If you are going to use a SAFC, I would be leaning towards a dual stage manual EBC (because of price and simplicity) I would have it so that on the low boost setting you can flick a switch which will take the SAFC out of the equation and therefore it will be a rich/safe tune for street driving. Then take your car to a dyno and get the safc tuned for the high boost setting. So when you flick the high boost, you also start using the safc and have this tuned to make more power.
If the safc is capable of having 2 tunes put into it then you could do that but I don't think it does.
You could do this just as easily with an EBC also but it basically comes down to cost for me.
I currently have a cheap as chippies turbotech controller from ebay. External gate with 15psi spring. My $30 controller is doing me just fine at the moment

Chris, for that exact same reason I would go with the electronic...
Get it tuned for the most boost you are going to run, say 18psi. Then you can run whatever you want under 18psi.
I would be wary if your fuel system or tune can't handle anything more than this and you're using a manual bleed valve. Yes the bleed valves have a tendency to drop boost off at higher RPM, but I've also seen them increase boost at high rpm, and also wouldn't want it to spike.
