blow-off problem

Code 52 is a knock sensor circuit malfunction and will cause severe operational problems. Code 51 indicates that either the A/C is in operation or the IDL switch in the TPS is open and is not a critical code although you should make sure that the error was indeed because the A/C was on or the throttle was open.

FYI - you can not set the timing with any codes present.

If the BOV is remaining open then you either have the spring too loose, the vacuum lines are not properly routed or the BOV is damaged. With a recirculating setup it isn't an issue at all as long as it's closed when boosting... one more win for recirculating.
