Does anyone know how to explain how this can be done, or is there a website describing it? My wastegate is ported on a hybrid t04e/stock turbo and im still get dangerously bad boost creep, i guess that an external wastegate would be my best/only real option left.



perhaps it just isn't boost creep. But here's how it goes. Basically as my gears go higher and the rpms go higher the boost simply keeps building. it never hesitates or slows down at all fikserxseven described it as "unlimited boost" and thats what it seems like. this is just boost creep right?



please help.

i don't think its actually ported.... if it still won't hold boost you need to put something to restrict exhaust flow

by hold boost you mean like keep it at a set psi right?

Does the actuator open all the way? maybe it only opens a little bit.

well here's the thing.



i used to have a crappy HD MBC in there (on/off valve, i never finished it really)



but anyway if i closed it (which would symbolize a non-opnening wg) boost would build super-fast and go super-high (well when i found out what happened i didnt let it get high i caught it right away) Sooooooo i dont think its not opening.



i have no clue anymore.



im just PISSED.

Completely remove the boost controller you have. Let the wastegate run off the spring and see what you get.
