In the coming months i am looking to get a protune when a few more parts come in. I have the listed mods and i am adding a ETS IC, UICP, LICP, MBC, and thinking about a external waste gate. Will a waste gate add power with a tune, is it something smart to do with a stock turbo?

 

Skip the external wastegate and get a 3-port BCS instead of a MBC.
