right , so i jus got a new set of intercooler piping , so i started to put them on , and i accedently
droped my bov ,like preety bad, and once i put everything 2gether, my car lost alot of boost
the boost is set to 8psi but only goes to 4psi and thats only for a second and drops back to 0
even with my foot down. ive noticed the bov is abit louder and makes a slightly different sound.


I HAVE NO LEAKS IN MY PIPING OR SILICON , i checked that a trillion times, and i dont think its my
wg , coz i jus got the turbo re-con'd like a month ago.

 

make a pressure tester. then pressurize the system and listen

 

check your turbo

 

Is the new piping much larger in diameter than your old piping?

 

yeh, my new piping is 3" and my old one was 2"

 

that could be the problem, are you hiting 4lbs much later than you were?

 

I agree...go back to the old piping. It should be fine unless you are running a shitload of power. As for the BOV, block it off (put somthing that blocks the hole completely off) and see if you get anything different, but DON'T leave it that way!!
