OverBoosting

[Rage]

Ok well i have a B16G turbo and today i was driving and went to overtake someone and my boost went straight up to 22 PSI obviously this was a HUGE surprise to me because it was set on 10PSI so i change the boost to high boost which is suppose to be at 18PSI and same thing straight up to 22PSI. i check the boost controller TurboXS dual boost controller closed it and turn it back to 10-18 and same thing. i check the Actuator hose and it was still on I didn't notice any rips same with the hose to the BOV and the boost controller
CAN anyone tell me whats up?

I had the same problem with my small 16g.... First off what size downpipe & exhaust are u using? As I was told 99% of boost creep or overboost issues are form a faulty wastegate/and or wastegate actuator. Basically your wastegate isnt releasing the gases fast enough. Try porting your o2 housing and the exhuast side of the wastegate to make sure the flapper can open all the way. If you scroll down through this topic, you will come acrost my post read that its got some good advise.
