I was driving today in boost about 7 psi and then a few minutes later I realized I couldn't really hear my blow off valve. I checked my boost controller and boost guages and it was only doing about 1.5psi.
My boost really just went away, even with the boost controller off it only does like 1 psi and the wastegate spring is a 3psi spring and it used to go that high before today.
What caused this? Did I ruine a part of my setup or is my boost leaking from somewhere? I thought maybe it was just my boost controller but it still doesnt hit over 2 psi with the boost controller off anymore.
Should I bring it to a mechanic shop? Would this be a lot of labour to find the problem at a shop that deals with turbos and performance
I just dont know what to do so anything is appreciated.
Thanks

 

look for leaks?

sounds like a blown coupler

 

boost leak somewhere. check all of your couplers... something that dramatic it's gotta be a big leak so it shouldn't be to hard to find.

 

K ill try and find it again. Just kinda dissapointed I can't run boost now and I have no extra money to bring it anywhere to be looked at.

EDIT: Found the boost leak, looks like a loose clamp on the coupler, ill just tighten it and see if it fixes it.

 

So I ended up tightening it and realizing the pipe wasn't fully in the coupler on one side. So I had to loosen it again and i'm about to tighten it, it's in such a small space for a wrench it will probably take me 20-30 minutes just to tighten this stupid clamp.

 

lol, I bet I know right where it blew off. I had to perform the same fix in a gas station parking lot, during a rain/sleet storm in January (in Michigan none the less), so I think You'll be okay

 

YA I'll be ok but i'm still working on it. I wish there was more space, I just got my HID's in yesterday and the ballast is kind of in the way but I don't want to have to take it off and put it back on too lol. I'll just keep tightening the clamp hopefully i'll be done soon lol.

 

Seems to be fixed. Thanks
