well one huge problem is you are hitting fuel cut. You will blow your motor, get a FCD or an rtek 7. An exhaust leak wont cause a lack of boost, a vacuum leak however will.

You need fuel. At the very least an upgraded fuel pump and an S-AFC. Better would be larger secondaries and the S-AFC to control them, as well as the big fuel pump.
If you are hitting fuel cut, then you need an FCD but fuel upgrades become VERY important with the FCD since the ECU now thinks you are running lower boost then you actually are.
Since you ported the wastegate, you're likely making less boost then you used to. You will need a boost controller (and the proper fuel mods) to raise boost.
