whats going on?

Ever since I did my exhaust and the MAS mod my car boosts to about 20 and spikes to about 22 psi .I dont hit fuel cut but it doesnt seem to pull as hard at that boost. I am still rading rich on the air \fuel.I still have the stock BOV but I think this is wrong considering I do not have a boost controller. this is my commuter so I need it as reliable as possible....also what should I set the timing at for the best performance and starting? thank you for any help

as for the timming it shoud be set at factory specs from what i was told.(5deg)

Try porting the WG hole so it doesn't creep as bad? Too much boost might be causing it to knock and pull timing. What mas mod did you do? Hacking the mas without compesnating with an safc is playing with fire IMO...
