Need boost help
Hi everyone! I'm new to the site and this is my first post. I just bought a 2010 ss turbo. I'm having intermittent boost problems. Sometimes when I step on the gas it has no boost, the gauge barely moves and it seems if I let off and then hit it again it works perfect! Any suggestions? Car also gave me a p2261 code (bypass valve I read)

Ok this is all new stuff for me! My first turbo. How would I know if my bpv needs to be replaced? Also might be a stupid question but is the bpv the same as a bov?

First thing I would do is bypass the vacuum tank under the manifold
PI: LNF- Intermittent DTC P2261 - Cobalt SS Network

They operate on the same principle although they are different in looks and overall function. Google it for a full explanation.

Please start with bypassing your vacuum tank first. I'm looking for pics but it's all taken down.
But to answer you other question. Our BPV recirculates the the blown off air back into the system. A BOV will vent the air to outside our. The stock BPV system is fine and easier to tune for.
But please bypass the tank first, clear the code, then drive it and see if it's better.
Then you can try to replace the stock valve.
Bypassing the vacuum tank is almost free and easy to do.

Ok it looks like I'm still having the same prob even with bypassing the tank. All the lines seem to be ok as well. So my next step is to replace the bpv. Any suggestions on what to replace it with? I should mention that the car has a zzp tune and zzp catless exhaust. I'm pushing about 23psi and my next mods are gonna be cai, pipes, then intercooler etc.
