If the cause is truely from overboosting, that's pretty crazy that a car with this low of milage, running only a psi more boost than Dinan is having this issue
Well the other problem is if "overboosting" where the cause, according to ign335i's logic, "99.9 of forum members" would have the same problem.
I wouldn't put too much into his conclusory statements.
