Free mod: removing emissions vacuum lines leaks boost?

[Deadly BlaZe]

Ok i was doing a little experimenting with the car today. I took out all the emission vacuum lines and after test driving it i only hit about 6 pounds of boost after 4k. I plugged the hoses back in and it's boosting normally now. I didn't think that boost leaks through those ports. Is it supposed to be like that or is something wrong with my car.

Sounds like you forgot to cap off some fittings after you remove the lines. What did you do with the EGR?

I didn't touch the EGR. But i just didn't know that you have to cap off the fittings or you'd be leaking boost. heh, learned something new. I think thats where some of my boost leak is coming from then because one of the hoses on the fittings just leads to no where. I'll be sure to cap them off this time.
