Do you see fluid around the tank after boost ?
I know you said you saw it coming out of the overflow, but that is normal for a HG leak.
Have the heads had a lot of porting done to them ?
Hopefully it is something simple like a tank, but I know about denial, I had a hard time admitting to sinking sleves in our first 500+ whp honda 1.6L. I even replaced 5 HG's over the summer so we could keep racing the car. Yea, call my insane...
The girls at Cometic began to know me by my first name. lol
