Sorry to hear about your ringland problem. Hope everything gets cleared up for you.
I live next State over, so I would REALLY like to know the name of this Subaru dealership...so I can avoid them at all costs.
Could you also let us know a couple other things as well...
1) What stage were you at, and who did your tune?
2) Was the CBE the only mod to the car? Did you have some sort of CAI other than stock?
3) What oil/oil filter were you using?
4) Were you rough on the car, or did you baby it?
