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...

what octane do you run?

This is on your NA-T right? I think you're getting some knock. What do your codes say?

heres my goal, i really just want my na-t to run good at stock boost without have all these guages all over the place, so i want to try to get my car running like it should stock without addons, is there anyway of telliing if the motor is gettin heatsoak without gettin all these guages? ALso i know this sounds stupid but how bad is this for the motor, cause i put alot of miles on my car.

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