o2 housing-Boost creep

[turbodohc20]

Hello, I am having a problem with boost creep. My car has 3" downpipe back exhaust w/o cat, 3" intake pipe, k&N, removed aircan and silencer, greddy type s Bov, 255 holley fuel pump. Now I've had the exhaust for months and have never had boost creep until very recently maybe after I added the 3" intake pipe. I have a second gen exhaust manny and a ported 1g o2 housing (not yet installed). My question is will that fix it? Should I port out the Mannifold? I've been told many ways to eliminate boost creep like the 02 eliminator or external wastegate or 34 mm wastegate flapper. I was wondering which is the cheapest fix and which is the most efficient one. Also I still have the stock turbo and I am going to get a fmic if that effects anything. Is it stupid to get a fmic without upgrading the turbo first?

Also I have a a/f guage that I havn't installed b/c I've been told there useless. If I get an egt guage how does that tell me if I'm running lean or rich? Should I get the 2nd gen MAF?
Thanks

Porting can help to reduce boost creep.
