At what point is a wastegate needed?

My truck is an 08 6.4 with the h&s, dpf and egr delete. I have the HD300 tune loaded and on wild I see a max boost psi of 42 and 55psi in exhaust
Back pressure. If I were to buy the WOP wastegate kit, what would be the highest I should see on ebp? Just wondering if it's worth the 800 right now? I rarely run it hard but when I do decide to play I want it to be safe

I was told by Rudys and Spartan that I dont need a wastegate at my level of mods, looking at what you have, you shouldnt need one either. If anything a BOV would be something to look at. I run 60-70 psi EBP so you are definately in the clear

I am also considering the same thing, but especially after Jeff's write up on the Elite turbo, I think I am just going to keep my eye on the EGB for now and wait until I save up enough for the turbo and studs and only pull the cab once.

I would recommend a wastegate if you spray nitrous or have a fuel system setup that requires one. If the fuel system and turbo setup you have are sized correctly, a wastegate is not needed.

Bone stock trucks blow up-pipes, and back pressure is nowhere near as high on a stock truck as it is on a tuned truck.
