#1. When operating a boost leak test with a greddy type- s installed does the lower nipple on the bov supposed to leak air? Because last time i did a blt thats what was happening.
#2. Car has no power when hit the gas. Low rpms are the worst between 1-3k it goes nowhere when wot. Had it boosting at 10psi then changed it to 20psi and felt no faster.. and when i gradually accelerate in any gear as soon as i hit 4k my wideband rockets total lean max and the car falls on its face.

Anybody have any advice on what this should be? Would a small /huge boost leak make this occur?

Just had My intake manifold gasket done because the leak was pretty bad in that area. but car still feels very very slow then what it should be

Thanks for any help
