ok, so i just bought an '03 wagon, and just realized something: I think i have a boost leak. i have the factory boost guage, and when i accelerate in any gear (as far as i know) the most boost i'll get is about .09. i'm pretty sure that means 9 lbs of boost. And when i get 500rpm or so away from redline the boost drops off. The car does not boost nearly as hard as some of the other wrx's that i test drove either. now i realize i'm retarded for buying it. Also, when i accelerate i hear a whining sound like a dentist drill when i get to about .0 lbs. At first i thought this was just the normal turbo sound, but now im not so sure.
any ideas on how to check for leaks? or should i just take it to a shop and see what they say.
p.s. i read some other posts on boost leaks, but i dont understand all this WOT, FMIC stuff like that. im a noob, so plz be nice.
