please help, i dont know why but when i adjust the SAFC2 it will affect car but when i drive in boost for while it seems not to work anymore, and the settings dont affect the car ideal or anything . it works again when i turn off car and start back up. i cant really go into boost or safc2 seems to go off, and once im in 0 or above it feels like bogging or something... right now i have stock injectors, but i will soon be putting in dsm 450cc

My question is would a missing link help with this problem? im only running 6-10psi right now i dont have a missing link.. Do i need one to solve this problem?? please help? Would a 2.5 map sensor solve this to?
