well first of all I'm the one that has the boost problem and was too lazy so i had angus racer look into it for me but here is the problem... i started having boost problems about a year ago and didn't know what it was so i bought the vishnu stage 1 kit with the ecu reflash hoping to fix it but the problem wasn't fixed so i put a perrin mbc in to fix the problem for a while but I'm really trying to fix it now so i don't wreck my engine. i put all the stock pieces back together (got rid of the mbc) and checked for the little bead piece in the vacuum line, that goes off the tee and to the turbo, and its still there so i'm confused? anyone know whats wrong? its an 02 wrx. thanks
maybe your boost controller is bad? mine went out on me...it would boost to about 14 then drop when i was WOT to 5 psi, then back up to 14 and backdown to 5 consistently. Replaced it...works great
