Why wastegate?

Just wondering what the benefits of putting an external wastegate would be, and If I should do it. I have an 08 f250, EGR delete, DPF delete, 5" straight pipe, and a 310 tune. And I'm only pushing 35-37psi of boost so I don't think I'd need one? And if not when would I need one?

IMO if you have plans to spray or upgrade to bigger turbos then you will need a wastegate. If not, all you need is a good tune. there is no reason why simple bolt on mods will require an additional gate...... if the tuning is correct.

Well I'm planning on either Doing a single s366 turbo, or a secondary s475. So I will be pushing more soon.

Bad backpressure sensor on the turbo's could cause an overboost senario.

I didn't pay attention to his boost numbers. What are your egts? Have you checked for leaks? That's a little low IMO for the 310

Your truck is pushing more than 35-37 pounds of boost.
Mine pushes just under 50 with a similar set up.
