So as i posted before i just installed the altered customs FMIC kit with no problems at all. before the install i had hardly any hesitation left with my crappy custom fmic kit but afterwards it feels like its back 100% im lost as to why it came back, or if it could be a boost leak and how i would tell the difference? im pretty lost this time around guys i thought i had gotten rid of this issue and ive chased down nd fixed everything else.. please help???
 
dont think its fuel cut that feels like literally hitting a wall this feels a little more mild. pretty sure all of the couplers are tight but whats the best way to check for a boost leak in the entire system?
