Sorry for the newbness but I feel like I get a good amount of boost. I have no CEL's either. I feel like it has to be the wastegate. When I have the car running, I can kinda move the wastegate a tad & the sound sorta goes away. The car honestly runs great other than a tiny bit of turbo lag. I'm a bit sick right now but tomorrow I will get some vids of inside the car & to where you can see a bit more.
