Instant Rise in Boost

[240dreams]

For some reason, my boost is crazily high. I have a TuboXS boost controller and i have it all the way in (lowest setting) but the boost is still way too high. What can be the problem. I looked over the hoses and such that run to the wastegate but didnt find anything.

How high is it? Does it boost fine with it off to 7lbs?

try running a straight hose from your downpipe to the actuator like stock and see if you have the same problem. If you do, time to rebuild the wastegate, if not then its a blocked line going to the BC or maybe a defective BC alltogther. Make sure no hoses are kinked

you mean hotpipe and not downpipe.

[got2b240]

yes :p thank you for correction nnkfws333, thats what i meant lol

Wouldn't having it all the way in be setting it on the highest boost?
