You don't typically see vacuum leaks, you need soapy water or something wet to check for leaks.

or starting fluid. if you do it right, when you hit a vac leak, rpms should jump up

well i think its the tune cause the car only jumps lean ( 20afr) and 2.5 rpm and at like the lower vac and til 3 psi of boost other then that it runs normal
