i just finish installed my greddy front mount and intakes today and go for a test drive, but it will not boost more than 6 psi. before i install both mod, it was boost fine (10-8-10). any one have any ideas on where to start looking or knows the problems? thanks

 

bov connection

 

make sure your hose couplers are tight and not leaking

 

what about it? i have a hks on the cold pipe.

 

all couplers are tight i check it. no leaks.

 

did u cap the stock bov location?

 

nope.... i just took off the vacuum line so it wont relief air. will that work or do i have to cap the stock bov?

 

You have to remove the bov and cap the stock tube. I used a rubber cap from home depot. That exact thing happened to me when I put my greddy type RS on the hard pipes and disconected the stock bov.

 

i will go buy it tomorrow what do you call that cap so i can go to homedepot and some. thanks for your help.

 

its the rubber feet used for the bottom of chairs, I got a 1" that fit over the short piece of hose that goes from the y-pipe to the bov. You could also go to an auto parts store and pick up i believe 7/8" heater cap.

 

yeah..i had that same problem.. it turn out to be my bov connection

 

Haha just incase anyone is wrong, check your pilled vacuum lines.

 

thanks man i fixed it it's the bov. i cap it and my car run like a champ. thanks again

 

thanks everyone for your help much appreciated

 

it would be 7 psi if it was the pills
