i know this is a stupid question but what does a missing link do and is it a must to have?? im just getting into turboscharged motors and have been doing some research on here and what just wondering if someone could tell me what a missing link does and do i need one. thanks for anyhelp

 

missing link = expensive check valve
look it up

 

sorry i should have waited to post cause i did look and found out that its usless if you have a chipped and tuned ecu which i have. also its not expensive i found a new one for 40

 

your chipped ecu is the way to go
