I'm constantly getting this P0299 underboost thing. It's also intermittent. I'm not sure how to go about this. I was wondering if there are people who are good at charts to see if there is any abnormal behavior in my turbo and N75 valve. I created 4 for of them entering the highway. Two on flat stretch, one on a small incline and one on a big incline. Not sure what else I could do. Local mechanics are good only in replacing parts, they can't diagnose anything without first taking things apart and taking money for it.

Highway 1 - a couple of traffic stops and highway short run
Highway 2 - short run back
Highway 3 - Slight incline/ descent, flat run until exit.
Highway 4 - flat then big long incline, then slight descent
