Wastegate piping size
I just dropped off my manifold to get the wastegate piping redone(creeping problems) and it has 1.5" pipe so would going to 1.75"pipe be enough or should i go to a 2" pipe?

It's hard to tell from the picture of your new mani, but it looks like your exhaust stream must turn more than 90 deg to enter the wastegate circuit. This will cause restriction and is similar to running smaller tubing and/or a smaller wastegate. If you can correct this, your 44mm might be better able to control boost.
