2016 Mercedes E400 3.5L V6 Turbo or supercharger upgrades?

Hi I was wondering if anybody can tell me what sort of upgrades I could do to my 2016 Mercedes E400 3.5L twin turbo V6, it’s already stage 2 pushing 450 bhp, 695 Torque. Does anybody know of turbo upgrades or even a supercharger? Thanks

You have the M276 3.0L V6 twin turbo, correct? Post your VIN for absolute clarity.

The M276 isn't often tuned. There is a C-Class owner who recently posted who used an AMR tune and broke a piston ring(s) and is walking away from the car. I think one or two other tunes are available, but caveat emptor, there doesn't seem be a large dataset to assess reliability of a tuned M276 engine. It's a higher than average risk endeavor in my view.

i looked into this and decided the risk was too great. Best to buy a C63 if you want more go.

A tuned m278 makes 600-700, Theres no way an engine with 2 less cylinders and smaller turbos makes more lmaooo

WHat is stage 2?

everyone has their own interpretation of stages and again a Marketing ploy.
Best to just say what mods you have done to engine.

The E550 with the TTV8 makes that kind of power with all the fixings. The V6 E400 at the most you will get about 540bhp and that is if you upgrade the turbos from Weistec.
A friend of mine here in Florida has a CLS400 (same engine as the E400) with all the goodies possible and it won’t make that much torque. I am kind of confused by the OP post. From what I can see you don’t get that power from just tunes. You have to upgrade the turbos.
