2G Boost leak?

[Dsmdaniel18]

I got a big 16g turbo and it’s not making much boost the boost gauge its self says it is but the turbo will barely even spool, I’m going to run a boost leak but I’m wondering what else can cause this I’m also running it on the stock smic if that might have any factors in this

Im pretty sure youre just dealing with boost leaks. Check all your couplers and run a boost leak test.
