depends on the air temp too.

It's called the Accelerated Warm-up System, and is used to quickly warm the pre-cat to lower emissions. It's not good for the engine though, and the solenoid that controls it (called the Air Bypass Valve) should be removed or at least unplugged. It's the cylindrical solenoid in top if the intake manifold. Look in the FSM for pics.

It helps to know what your car is since S4 and S5 have different boost and different gauges, but stock max boost is just below the top of the scale for both. If you have any plans for mods, the first one you should do is a decent boost gauge that will give you actual readings.

Just wanted to let you know, NZ, that I accidentally "discovered" that the air bypass valve doesn't do squat for the accelerated warmup system, at least on my NA. My relay and valve are off of the car, yet she still kicks it up to about 3K on a cold start. BAC is doing it all...

That's funny, coz others have reported the ASW idle speed drops quite a bit when the solenoid is unplugged. The BAC valve was doing some of the work but not all. Weird...

FYI, my JDM car (no pre-cat or AWS solenoid stock) jumps up to ~1500rpm for ~10seconds after a cold start. I presume this is simply a milder version of the system US maodels have.

hey i hate u dammit i want a right hand drive 7 haha j/k, its a s5 with its warm the boost goes up to about where it says x10 or 10x...and yea i'm sure the a-spec 7's are tottaly diff then j-spec and it ****** blows i hate it

Actually there aren't that many differences and most of them are minor and trivial. they're mostly emission-related and don't affect performance, and they usually get removed anyway.

J-Spec engine is the same as the "A-spec" engine besides a few emissions different. Oh, and the intercooler has a different sticker...
