Thanks for the response, Grimm. After looking through all the posts on the subject, I think I am experiencing Safety Boost. It is like someone throwing a switch when the full-on boost stops. And then I am right in the 5-6 psi range that is described in the posts. Any idea why this might be heat related? The discussions usually say that the engine seems to think it is still cold, but that is when I am getting the most boost. Then after the engine heats up, I go down to the 5-6psi range. Of course, it is quite possible (I think) that there is a boost leak as well. Which I think would be more likely due to heat fluctuations. But the Safety Boost just seems to fit the symptoms so much nicer and my gut tells me that's it. Anway, I will be calling the dealer tomorrow and having a little chat with these guys. We'll see what they have to say. Will let ya know.. Cheers R
