MS is run on a MAP sensor, you delete your AFM completely. MS handles fuel and spark. Boost is handled by your wastegate, unless you have some sort of electronic boost controller, yada yada.
Not my first turbo rodeo, but thanks for your input. former WRX owner here. it just appeared in the pictures that he was running a manual boost controller, but i read matt325is write-up on using the typhoon controller, not sure if he was capable of putting that in a MSPnP for me. It's also a little vague in his posts to whether he's running a knock sensor or not. Here's a spy-tip for you, i joined this forum before you, but only have 10 posts; I read a lot.
After further reading, i found the MAP Daddy 4bar setup on diyautotune.com
I'm curious to know if that location on the oil pan ended up working for the return line? You've got a very impressive setup todd, i'm in NorCal and would love to come by the shop someday.
