[917mgte]

going down the street the other day hit boost and car keeps cutting out any help

 

[hvyman]

[917mgte]

an exhaust and bc other than that bone stock

 

[hvyman]

bc=boost controller? how much boost.

 

[917mgte]

right around 8psi

 

[adampecush]

you have a boost leak.

 

[917mgte]

thats what i thought but i recently ran a boost leak test and the system held well but my boost gauge says its holding constant boost

 

[adampecush]

how did you run a boost leak test?
Even if your gauge stays constant, you can still be losing pressure through a hole in one of the rubber elbows. Same thing happened to my car; it was the elbow directly off the compressor discharge.

 

[Reaper Man]

you have a boost leak.

this would be my guess as well- especially if you're basically running stock boost

 

[917mgte]

took a piece of pvc pipe but a rubber connector and a gauge and put compressed air into the system and it holds

check the vac lines to the boost controller sylanoid. mine did this recently and would buck

 

[917mgte]
