I have a 2010 ss. GM stage 1. HKS blowoff. Injun cai. Over the past few months it will drop to 5 psi periodically from 20. Last couple days it's doing it constantly. Go to work in the morning and it's fine, go home at night and it's at 5 psi with a weird fluttering sound from the turbo. GM mechs are useless, they say there's nothing wrong! Help!!

 

first check for blown off charge pipe or intake on turbo. Then swap to a stock BPV. check for more boost leaks....

 

Are there any codes?
Running a bov on gms1 is a major issue
Gms1 has no way to adjust for the un metered air your blowing out every time you let off the gas.

 

....yup. bov and stock stuff is a big no no, since 2008 Get a forge BPV. you still get that sound you want but it is safe.

 

Thanks everyone! Anyone have a Forge or stock they'll trade for my HKS?

 

Forgot to mention that I have Dejon Piping, will a stock BPV bolt into it?

 

the bpv is in the stock turbo, not that charge piping. You'll have to block off the bov flange and remove the block off plate on the turbo

 

Ok thanks, could you or anyone else share a link to an affordable BPV that would work? I bought my car previously modified, don't know much about this stuff.

 

Ya there's a code. Gonna bring my reader home from work and check it tonight. Thanks!

 

Can you share a link to the forge BPV that would work? Will that have to be installed on the turbo? Thanks!

Cheapest place I found it. Got my SS one there and, same exact one fit my Escape.

 

I think dejon **** the bed and isn't around anymore.

Hit up ZZP they may have the bov block off plate for you.

 

Oh...found a pic



Looks like you could....just use a rubber cap and tclamp it off.

 

Hey thanks!

 

You HAVE to tune for a BOV and it's uselss until you go big turbo. For a BOV you would need a BPV block off plate, a BOV, upper IC pipe that has a BOV plate, a lower IC pipe that has a MAF plate, and a tune.
