Boost trouble!!!

Recently i Got my bb 50 trim installed. Before that i was runnig the stock turbo off of my Apexi AVCR.

I had the evc settings down. The car held boost strong up to redline. But i had to reset it because i have the 50 trim now.

My problem is no matter how low i set the boost or duty im hitting high boost like 30 psi i know thats to much boost. But no matter what i do it seems to jump up to 28- 30 psi. Shifting early is the only way i can keep it under 20 psi

ive searched and found threads kinda similar but they all had mbc.

Could it be from a possible bov leak?(i was using the stock plastic switched it to what i think is a ebay types s)
boost leak?

I guess i have either boost creep or im spiking

my tial 32mm wastegate dumps out so i dont think its a boost creep.

Also when i rev the car in netural the afr is really rich. I idle about 11-12 then when i rev it high and the rpms drop it get really rich (18-19)

at idle my vac is about 7psi is that normal i read that it suppose to be 17 or something

please help guys
