Check engine light comes on whenever i come on boost car goes on limp mode

Hello i just boosted my h22a i have 450cc inj and 255 fuel pump and im using an afc neo on a p13 to tune it but when ever the car reads a little bit of boost lets say half a pound my car goes on limp mode and wont accelerate or nothing why is that any help on anything i could do please. could it be that i dont have a missing link for my map sensor? Thank you please anybody help lets just say im a newb and this is my first turbo car :

+5 ----'s not going to tune itself

read the stickies in the top of this forum and the forced induction forum. It will explain what components are needed for what type of management ie fmu/chipped ecu/afc. You don't just start throwing components that may not work together like a missing link and an afc. Otherwise keep trying to drive it like it is while looking for someone to hold your hand over the internets and enjoy looking for a new h22 soon

how much boost are you trying to run? A P13 ecu is not expensive to chip and throw a basemap on.

get rid of the afc and buy a real fuel management i.e. chipped ecu

What is your AFC numbers? It should be like -40 and on. DO you have the correct sensor type set in your afc nerdo? DID YOU READ THE NOOB SECTION YET? NO ONE WILL HELP YOU IF YOU DON'T START SOUNDING LIKE YOU HAVE AN IDEA WHAT IS GOING ON!!!!!!!!!!!!!! I know i have told you once already to read engine management newb section. DO IT!! You don't need a check valve for your map and you would know this if you had read the newb section, its already answered for you.
