Boost leak is after the turbo. So when your leaking air the turbo is spooling up more because the wastegate is not opening and sucking more air past the afm.
Think of it this way, instead of the turbo working for only 15 PSI, it has to go up to 18-19 PSI to get the desired 15 PSI.
Turned out to be a couple boost leaks. Pulls like a freight tain now. Only problem now is during wot at the top of the rpm range the vf signal goes full lean. At any other time my vf is perfect. I thought i remembered reading a while back that vf doesnt monitor open loop so maybe im alright? In any event i should be hooking up the wideband today to see how its looking. The safc might not even be needed i feel like
