I eventually plan to go fp black but i definitely need to upgrade the stock o2 housing. I am doing a 93 tune soon so i was just trying to do some things before hand but it looks like i may just do the dump and seals before i retune and go that direction. Im trying to trap 123-124 on stock 8 turbo just as a goal of mine personally. Im basically between the jm fab and map o2 dump right now.
