So I got around to leveling it out while trying to get my p/s to work. And now the turbo is really loud. And it doesn't whistle anymore its more of a air sound. I would say like shhhhhhhhhhhh. Also I only get 8psi. Boost controller is up all the way. Can't boost more than 8psi. Used to be set at 10psi and held till redline just fine. And I have gone up to 12psi when I 1st adjusted the MBC.

S4, 3"TID, BNR STAGE 1 turbo, HKS MBC.

What could be wrong? No leaks I checked everything, and I only removed the TID.

 

Update: I moved it back on its side. Turbo whistles and boosts right up past 10psi. I had to readjust the controller again. Could it be it gets more air with it leveled out? But why would it only boost 8psi?

 

sounds more like a leak, scratch on the inside of the intake hose or something?

Depending on the angle before, you could also be getting a different fuel mixture to air ratio now.

 

Yeah it definitely sounded like a leak to me. But it shoots straight up to 8psi and holds there. It doesn't fluctuate. But why wouldn't it leak when its upright. I also checked everything and everything is good. Plus it doesn't do this when its upright so I think its the turbo.

What would a different A/F mixture give me? That would cause me to boost less? My turbo can't boost more because its sucking in more air?

 

Any idea's as to why I get less boost and why my turbo is louder. All I do Is rotate the MAF. I don't touch anything else. This is so weird,

 

yeah there is a leak when it is upright.
