no way! just downshift first with the paddles, or to get the car to do it for you (in auto mode) quickly press the gas pedal to the floor and let up and it should recognize the desire to accelerate and downshift the transmission for that purpose. then go ahead and punch it!
I had a similar experience to what Skym is having in the car I had before my RA. I was using a TiAL bov. My bov would flutter when the boost was 5psi or less, but would work normally above 5psi. This was for exactly the reason that chi-town mentioned above, just not enough boost to allow my bov to open up the way it normally does. I'd expect that the issue Skym mentioned is exactly that.
However, exyia's problem is a totally different animal. I'd re-route the AEM boost gauge line to another place asap, try to tee off the line on your intake mani.

random question but i'm looking around for a stock evo x bov for sale.. not really good at finding the right page yet but could anyone tell me if ams bov is the same thing. if it isnt could you hook me up with a good place to get one/suggestions. any info is helpful. thanks guys.

I have changed the tubing and tapped a boost gauge into the bpv line. I thought this was the correct way to do it (My gauge seems to bounce up to ~21 psi on WOT and sits at ~ -20 psi at idle (vacuum))?
Please take a picture and show me where else I can tap the gauge into if there's known problems (There's only pictures of the Evo X installs and the RA does not look the same. Some lines and the BOV is fitted differently).
Also please tell me what kind of problems has arrised that you are mentioning.
Thanks.

if a hose is coming loose, or even worse completely off, in the bpv or wga routing then the valve may not be opening at all. this means that the compressor is continuing to spin and push more air and is slamming it into the closed throttle plate which, in turn, will cause air to back up in the system very quickly to the point where it is actually bouncing back and creating a "reverse flow" effect and trying to force the turbo to spin backwards. this can cause major issues including very rapid failure of the turbocharger.
you can also try looking up the phrase "turbocharger cavitation" in google for more information if simply searching for compressor surge isnt yielding enough results
it is very highly recommended that you find another hose to tap into for your boost gauge as tapping into the bpv line has been shown in a few other mitsu evo/ra applications to cause issues as well
