strange. I get proper boost now 15-18 psi at the proper time, but i was passing someone on the highway today and the car felt like it was a...honda civic, it had no *****. and all i hear is a wooosshhhh sound in driver side area under the hood when the car is under load, not reving in neutral tho. I am having a hard time hearingleaks when i am doin the tennisball method of boost test. any suggestions on where I should look or what might have happened?
thanks.

 

if you can hear the wosshhh sounc clearly, you should able to find the leak without tennis ball thing. check all the hoses. sounds like a hose disconnected. it will ruin your spark plugs soon. let you friend rev the car and try to listen where the wooosh coming from.

 

deff get on top of that, you dont want to be replacing all your plugs for an easy fix like a new vac line.
