    Dual wastegates or large single

    Ok so the turbo kit came with a 38mm Tial WG and from what i read the 38 WG will not be able to control the boost of the new turbo at lower boost levels. I want to stay around 10psi at first. Should i just go with a single Precision 60mm or just add another 38mm. The boost will go up once everything is proven good. After everything is good will be adding a AMS 1000, and just keep the 10psi spring and have the controller set up.

    Either should work. I'm adding a second one to dads truck for the same reason, and it's just easier to add another bc I have an extra one.

    The best advice I have ever heard:... Only take B( . Y . )ST advice from someone that is CURRENTLY running a turbo setup close to, or bigger than what you want......

    I'd say go with a single larger one jut to make it easier to plumb in the controller. Granted your gates wouldn't be on separate sides of the engine bay but I have vacuum/boost lines going all over my engine bay for my controller and it looks like shit!
