necessary mods for pure turbo on m340?

I have a 2020 M340i xDrive and recently purchased a PURE850. I was wondering, what modifications are necessary to run upgraded turbos with no issues?

Since this is my daily, I'm looking to push as much power as possible without reliability becoming a problem. I'm planning to run mainly pump gas, since it is my daily, but I want to be able to run E85 on special occasions.

Currently, the mods that I have on the car are:
- Active Autowerke Catted DP
- Dinan Intake
- AWE Touring Exhaust

I was planning to take my car to @stimikey for a custom tune, I've read good things. Anyone have any experience with his custom tunes?

Any and all help is appreciated!

I have previously had experience with a custom tune on my F10 M5 and a Bootmod3 on my F90 M5. Bootmod3 is by far the most flexible and easiest to live with for a daily driver and occasional use with E fuels. Just got mine yesterday and will be installing and testing it today and tomorrow.

Tune + Downpipe + intakes + Heat exchanger are a must in my opinion.

I have a friend in a 2020 M340i with a Pure800 turbo on his car. I gotta ask him what else he has done to the car. I would assume an Upgraded HPFP would be needed.
Not sure about any other fueling needs....

can't seem to find any options available for HPFP, only see them for gen1 b58

if you could find out what your friend has done so far, that would be amazing

Check this post out. Page 2. The whole thread is informative but specifically check out post # 35.

https://g20.bimmerpost.com/forums/sh...highlight=HPFP

Looks like a HPFP is not needed. They are talking about a Pure800 setup while you have the 850. So I'm not sure if that would change anything.

You won't need a hpfp because the transmission would be slipping before you hit the fueling limits with a Pure 850. B58 Gen 2 already has upgraded fueling from the factory. People just add port fueling when they need supplemental fueling. And my personal opinion is to avoid mike botti if it's your daily. He tunes super aggressive which is great if you want to break some records but not when it's your daily. Visconti Tuning would be my choice. Which is who tunes almost every fast BMW in NY. Or else tuned by payn.

Why do you need 850? Enough 800. You will reach the trance and fuel system limit and on this turbine,

ZF 8HP51 would not hold this power. First that you should upgrade is transmission if you want to upgrade your turbo.
