hey guys i have been having this weird problem where when my engine is cold i can boost to 9psi (cold meaning like after 15 min of warming up) then as i drive on a long trip such as an hour, i start loosing boost till i am around 5-6psi, what can cause this? i have no boost leaks that i can find. I can let the car cool off and then it's back to a solid 9psi. Now someone had told me it can be the cps, so what are your opinions? or has anyone ever had a problem like this?

heat soak causing the engine to pull timing...

check how hot your engine is REALLY getting, the stock gauge sucks...

BTW, I love your Avatar. I couldn't read my owner's manul, but always thought that picture probably meant something like "No Drifting" :)
