So since the beginning of my journey with this car, I've noticed what I would call "turbo surge" when at high speeds. Say I'm going 80 (legal in MT) and I want to pass a trucker before the exit, I'll step on it. When i do this, the car seems to surge and you can hear the turbo/intake noise pick up, and then drop. repeatedly. If I remember right I could even feel when this would happen, as the car would somewhat surge in acceleration. It's gotten to be hardly noticeable now, but I remember back then I could feel it. I can only feel this in 4th or 5th, so I'm trying to figure it out. I don't have a boost gauge(its in transit now) so I'm having a hard time telling what's going on. I somewhat think it's the wastegate letting too much by intermittently, but then I've also wondered about the bpv. Maybe that's letting air go by? The car has a nameless catless uppipe & downpipe. The only other thing I can think of is the hacked snorkus mod, and some aftermarket ~red~ intercooler hoses. Has anyone heard of something like this before?
