I just bought my 2002 WRX a few months ago and now I've been having random boost spikes. It doesnt happen in first or second gear but when I try to give er some juice in any higher gear my boost will suddenly spike up and come back down before going back to normal. Even if I have cruise control set this still happens if I'm going up a steep enough hill. I'm not a mechanic but my internet diagnoses is that this must have something to do with my boost controller or solenoid? Any help and advice please!

1) Pull the ECU calibration currently on the car and look at itAuzzyP said:
2) Pressure/smoke test
