if it bogs in the mid it can be plug wire. sometimes they do that under load but usually before boost. cheak for boost leak if you don't have something to tune the afc with then leave it alone like... egt logger etc.

sounds like fuel is another problem you need a fuel pump. also you could rewire it. there is another ghetto method put a clamp on the outlet of the fuel line this won't let it bleed as much pressure and it will give you a little more.

um if you need hands on help im at the beach and i'm free
