Default my chipped 1.8t is only boosting to 10psi and then quickly drops down to ~5psi... it will
drop whenever it gets anywhere up to 10psi..

i usually hold ~17psi and spike to 20psi....

it now wont even manage close to 10psi,
i changed the bpv and checked for leaks....

cant seem to find what the problem is.
