Yeah, I saw those too. I was hoping to get a little more insight from someone who may have actually had the issue and resolved it. Is there a "best" way to diagnose a boost leak? Like I was saying, I can only replicate this at the track, so I'm trying to avoid the 'take it to the shop, they say its fixed, take it to the track, find out its not' game.
Crazy thing is, the dealership quoted me $640 to replace the diverter valves! I would have been very mad if I had paid that only to find out it didn't fix it. While I didn't pay that much, I did spend $100 on parts to do it myself.
