HKS VBC problems!!!! Please help

[V8kller]

I just hooked up my hks vbc and it doesnt work. :aigo: I cant adjust boost at all. I Called up HKS and they said that i have it hooked up right, does anyone have any suggestions if so it would be greatly appreciated.

what kind is it(e.g. evc IV V etc.). you might have a problem in the wiring harness for it or have vacume hose issues(backwords, not big enuf/too small). double check all the settings too. did you go through all the setup testing stuff first so it can learn your boost curve?

It is actually a mechanical boost controller. and i checked for leaks and for kinks but there were none. Im starting to think that it may be a faulty valve.

could be the spring on the waste gate controler.

 

[V8kller]

Is there anyway to tell if that is the problem?

 

[boost fiend]

did you have any boost problems before the install??? try checking loose hose conectors.

No the car boosted just fine and had no vacuum leaks. i cant figure out unless the valve itself is bad.

Is it on backwards?

No ive tried it hooked up both ways and still no luck.
