ok yesterday i was driving my car and it was hitting 24psi like always... then all of a sudden i get into it and its a 15psi then down to 10psi over the night... any ideas on what might be wrong with it?? i dont see any lines that r blown off... BOV is still opening and closing properly... and ideas?

 

i remember something with the tabs on the stock intake causing suction i think... i dont' know if thats it, but i think it might be because in the other occasion there were no leaks... i could be wrong, but check the tabs on your intake

 

Yeah, do you still have the stock intake, and do you still have the clips holding down the snorkel that connects to the front of the engine bay? If you have the snorkel still, and it's not clipped, then it will cause major boost loss up around 5500-6000rpm.

 

update?

 

do a boost leak test
