Hey I have just gotten a 2004 WRX from my uncle. It runs great except the turbo constantly pulses. It is most noticeable driving at a constant speed and then slowly accelerating over 3 thousand rpms. It sounds like maybe the waste gates are letting air our prematurely but I have had a few people look at it and they can't seem to find anything wrong. My uncle had some after market modifications done to it including some exhaust work, and a new up-pipe and down-pipe along with a GReddy system installed. I have heard that the GReddy doesn't work well on that year of WRX and have recently uninstalled it and put in a stage 2 engine management system in it. I think the problem has to be mechanical because the turbo still pulses with the management on or off. If you have any ideas or further questions please let me know. I would really appreciate it. Thanks a lot.
