I'm hard intot he throttle all the time and have been out at a track day and have not experienced this problem I have heard of this happening when people are low on gas and when they turn sharp fuel goes to opposite side of pump or something like that...

cuscosti, what kind of mods do u have on your sti? if u have an aftermarket turboback exhaust, you will get boost creep, fuel cut, and a cel. the only way i know of is porting your wastegate on your vf39 turbo. or you can get a chip, which will probably eliminate boost creep(im not fully sure, i met a guy who did this, and there was no boost creep with his catless tbe)

the only cure to this is to go with a electronic boost controller. There is no other way so far. Got my turbo port and polish and still hitting boost spikes even with a manual boost controller from vishnu and turbo xs. Boost spike only happens when you open up you exhaust side from the turbo back alot more air flow.

Me and WRXBOY tested the boost controllers together. We came up w/ a solution when a member named DaveWrx never really had any boost creep w/ his Blitz SBC-ID. So when WRXBOY gets his boost controller in im pretty sure that would solve some problems.
