boost leak?
So i am having this issue with my sr20 where it only makes around 1 or 2 pounds of boost at around 4000 rpm and i was wondering if its because i have a boost leak. ill link the video im also curious if a boost leak would have the same effect as a vacuum leak meaning it sounds cammed when the engine is warm

Your boost gauge is hooked up pre-throttle body so you should change that so you can get a vacuum reading with the throttle plate closed.
Your car isn't going to make boost just free-revving. |

You are only running about 10inHg on vaccum, should be more like 20-22. I would definitely say you have a boost leak.
- you arent going to make any boost sitting idle, gotta drive it to do that. - Is your MAF setup draw through or blowthrough? - are you familiar with how to do a boost leak test?
