whenever i am producing boost, i hear an air noise that increases with the amount of boost. someone suggested that it might be a leak in the intercooler pipe couplings, yet i managed a 14.1 on the quarter, so i don't think i'm losing power. any ideas?

Do you have a boost gauge? What is it showing? Do you hear the noise when you are accelerating as well as decelerating?

no boost guage. aquiring one soon. only hear the sound when accelerating.

First place I would check is the rubber ic pipes. Take them off and look them over real good. You may want to flex them a little to see if there is a big hole in there somewhere. If that's not it you're probably going to have to track down a hose that blew off somewhere. One other place you could try is the y-pipe. Being plastic, they have a tendency to crack also.

gracias mi amigos. i will check the couplings for the intercooler first thing.

also check for one of the blow off valves partially stuck open, it does happen

Thats kinda what i was thinking. The blow off vales have a surge sound when boosting right before they vent. I thought there was something wrong with my car the first time I heard them. But I was getting full boost so ...

check the rubber coupler coming off of the y pipe
