Boost problem

[fat313]

Whenever i on my HKS EBC 2, when on boost, my boost will be jerking or fluctuate from 0.7 - 0.9 - 0.7 - 0.9 bar .... than will drop to 0.5 bar from my boost gauge?? It doesnt matter what boost i am on. Anyone knows or suspect what is trobling me? However when i swith off my ebc, on stock boost, my car will run fine. Do you guys think my ebc is stuffed?

how many bar is stock boost? cause i am getting 0.5 bar for stock boost. Is that normal?

[Guest INASNT]

0.5 bar is 7psi which is stock bost with everything else stock on the car

mods are Big intercooler, full 3inch exhoust, BOV, S-AFC, RSM, Electirc Boost controller.

Anyone knows how i can stop the jerking boost?
