I have a Turbo XS HPBC. I adjusted it per instructions and per the instuctions on robs site i hooked it up. But im getting boost creep like no other. Does anyone have the TurboXS HPBC? How did you end up dialing it in? It seems like no matter what settings i set the controller at my primary boost does not change. only my secondary goes nuts. :T... I know i must be doing something wrong... any advice?

 

in reference to your boost creep, a boost controller won't really help that. the wastegate on the stock turbos need to be enlarged.

 

Yeah, if you are actually observing boost CREEP, then a boost controller will do nothing for your problem.

 

I've got the dual stage HPBC. I also had boost creep until I put a cat back on. I was running full non-seq on a ported motor with BNR stage 3's. That included a ported waste gate. I creeped to 15psi no matter what. Now with a mettalic subtrate cat I got it dialed in on 12psi (low) and 15psi (high). Just needed a little back pressure...

 

I had no boost creep up untill i installed the Boost controller. I was only able to get 8psi so i added the BC in hopes of getting back that 10... But it is being an uber pain.
