I have a 2012 Chevy Cruze Eco MT 67K miles on it.
Right now my mods are no resonator and no muffler, and a trush glasspack on it with dual tip exhaust.
Eiback Pro lowering springs.
Clutch Delay valve delete.
I had a cone filter on it and i had the bvp solenoid bypass(so the bvp will be manage by vacuum and not the computer)
Decided to go with the stock box until i get a decent SRI.
For some reason, dont know if my boost gauge is faulty but it wont go past 8 psi.
The bpv solenoid was not the issue, as i had it done for almost a year.
But decided to put back stock( as i read and found out what it can happen)
It was doing 13 before i change back to the stock airbox.
Threw a new line directly from the T in the vacuum source to the boost gauge.
Still wont go past 8 psi
Cleaned out both map and maf sensors.
There is oil on the pipes as i did have the valve cover burst disk go bad, and the check valve on the manifold is gone.
I think either the hose is to thin and the vacuum is sucking it shut, or there may be a vacuum leak somewere, but cannot hear any leaks.
So any ideas as to why i cant hit full boost would be appreciated.
If i left out any needed info, let me know.
Note: running BKR7E copper plugs (tried BKR8EIX gapped at .028 but get blow outs)
boost gauge is a cheap ebay brand.
