Thanks. Good luck to you too. It always runs fine except when the low boost condition occurs, and even then it feels pretty good. The track is brutal on our cars I guess.

Also, just to complicate matters, I don't think my WG is opening completely (which would cause high boost, not low boost so it doesn't make sense).

Check it out. I made this video shortly after my track day when my car started doing it's weird low boost thing again.

 

No thats NOT normal... WG should open alot more.. You can see in this video


Something is blocking the WG door. Remove your DP and check. it maybe the DP...

and to checking for boost or vacuum leaks, You can smoke out the intake and exhaust system to find leaks easily...

hope this helps...

 

I saw that video when searching youtube too but since that's not a stock WRX turbo with a stock DP attached, I'm not sure it indicates that I have a problem.

Smoke is a good idea but I don't have a boost leak, at least not consistently.

Still need to make a new log and ask Ed to look at it.
