I have a 97' GTP and it will not pull full boost lately. It has got worse the past couple of weeks. Do you guys think it could be a clogged cat?
 


Is there a typical place that you'll find a vacuum leak? A certain line or component to check first?
 
its usually the vacuum lines that run around the blower, mainly the rubber T that butts up to the LIM.
 


You think it would be wise to ditch the rubber lines and use silicone hose instead? It's been done on DSM's for years, since they've got vacuum lines running in dumb (i.e. hard to reach) places.
 


i was pretty hammered by the time i left that first post clogged cat shouldt have been there But i hate cats and blame every thing on them
 


Holy sh!t thats expensive! You can get silicone tubing made for RC cars and planes for about $1/ft at the hobby shop. I've used this tubing in applications that run in the 500-600 degree range. Many hardware stores and plumbing supply places will have brass T-Fittings
