if your reffering to voots car...its an ej207, could run 25 psi day in day out if tuned correctly. But manual boost controllers will = boom

edit : just read the first post, you could set the boost controller to 30 psi but it wouldnt get enough fuel because it isnt tuned and itll pop.

I'm no mechanic... but as far as I'm aware, the "engine" doesn't "put out" any boost at all...

could driving on "low" boost do damage as the car hasn't been tuned for it?

When he says "tuned to run boost up to 1.5bar", he means that his car is tuned to run boost up to 1.5bar. Meaning air:fuels, and timing etc are all set and tuned appropriately all the way to 1.5bar... including the "low" setting on his EBC (15psi)

dont mind me while i hijack your thread :P

i did the same thing, fitted a boost gadge and manual boost controller

seems my 04 sti is boost spiking to 20pound then sitting back around 17/18pound...

this is in hot weather too, so ive set the boost controller to lowest possible, will a tune fix the spikes? i thought a controller might smooth it out a bit

Manual boost controllers are SHIT!

Set it on a hot day = Overboosting / spiking on cooler days = boom or boost cut on a cold night

Get an electronic boost controller if you're serious or run stock boost control (which is 1000x better than a manual bleed) if you don't know what you are doing.

manual boost controllers (bleed valves) are for S13's. They don't belong on modern cars and will cost you a motor

subaru gdb boost control solenoids are not much better than a manual bleed valve.

mine was tuned to 1.3 bar through the autronic,

but on a cold/dense night it has been known to hit the 1.9 bar boost cut.

tried another brand new factory bcs = same.

have now purchased a grimm speed direct replacement bcs and needing to retune.
