So i went to the dealer today to pull some codes myself ( i work at a mazda dealership)
and i came up with
1) 0139 o2 sensor low cirsuit input (catless downpipe)
2) p0234 Overboost condition
3) p0235 Wastegate A low condition

The tech said 2 & 3 were related to the overboosting...but i only have my ems set to 17 and i might spike 20
ANYTHING ELSE WRONG that i should be worrying about???

What does your tech say? I am sure the catless downpipe has something to do with your overboost.

He said the overboost was from my ems. That the ecu knows when the car is makin more boost than factory. He said if i had gone to another dealership they would have called it in to mazda warranty and given them my vin # and they would've voided my warranty when i would come back for ANY warranty work

easy fix finkle, clamp your map sensor so the ecu can only see so much boost but the catless downpipe is just something you'll have to live with

I called Corksport about the P0139 code. They said there was a fix but never called me back. I cleared the code and forgot about it for now being that I have only driven the car 700 miles for the last 2 months. The overboost shouldn't happen with the Standback. Did you lower the map clip in the boost tab? I was getting some spiking and it went away when I turned that back up to the CP-E setting.
