Im new to the external wastegate game - im just wondering if anybody has some guidelines on wastegate selection and the pros/cons of larger and smaller wastegates comparatively..... :whip: Im looking at a GT4088 to go with it.

so are there any drawbacks/advantages of going with a smaller wastegate? I assume that depending on turbo exhaust trim/AR and estimated HP, you would have a certain limit for wastegates, right?

So does a larger wastegate have trouble controlling boost at lower hp settings?

the smaller wastegates cant control low boost as well as the bigger ones. If you run high boost or a stiff spring then you will be fine with a small one. If you run a giant turbo with a 6psi spring, and want 6psi it will probably spike and stuff.
