cant get control of my boost! ???
 

having a few probs with my my99sti after fitting 20g and a few other bits and bobs. car runs on apexi

car runs fine at 1.6 bar but if i run any lower boost value it really dont like it and wants to over boost and fuel cut etc etc. the weekend is almost here and i'm going to look into this as its bugging me. (been this way for 2 months,just not had time to look at it) i have cheak pipe work, restictor, leaks.

poss something like bcs faulty, dia of vac pipes to large, restrictor size incorrect??

just wonder if anyone else has had an issue like this. if you have please just reply with what you prob was and what the fix was
