I am new to the site, but I have been around the N54/E90 forums for about 10 years. I have 2009 E90 335i that I bought new in Germany. I went the full 'stage 3' path back before there were any real upgraded turbo options. Fast forward a few years with some different life priorities (had 3 kids, built a house, job changes) and apparently I'm completely out of touch with the n54 tuning scene. I really like that this forum seems to focus on technical details with a really knowledgeable user-base, so I'm hoping some of the experts here can help me catch back up.
Current performance mods:
My car is my daily, runs ~100 miles per day, and is sitting at ~120,000 miles total. It has been tuned since about 40k, so things are starting to run out of life. The turbos have had a nice wastegate rattle for a while and the stock clutch is finally letting go. I'm thinking it's time for an overhaul and to just try to knock the major things out at once. Thus far I have done all of my own labor, but I'm planning to have a shop do the work this time.
Here is my general assessment of things currently. Any input is appreciated.
Any feedback is welcome and appreciated. I am looking to pull the trigger on this in the next couple weeks. Also, if there are any professionals in the Maryland/Northern Virginia area, shoot me a message.

- New MHD tune, with maybe a JB4 as an overlay.
- For daily driving, reliability, and a buy once, cry once mentality > single turbo kit. I am looking at the CES and Speedtech kits with a Garrett GTX3582R GEN2. It sounds like fuel and power goals really drive the kit and turbo decisions. With that said, it looks like 600-700 HP is a reasonable number for stock internals and that's my goal. I'm willing to go up or down if that's the consensus. For fuel, I'm hoping I can run 93 daily with E85 on occasion. It seems like the platform has moved past meth, but I'm open to that as well.
- I don't fully understand the fuel situation currently. I would like to stick with DI. Will a LPFP upgrade cover 700 HP or is one of the HPFP 'barrel' kits required?
- I'm reading a SMFW is required for a build like this, so I'm eyeballing the Mfactory SMFW and a XClutch 9" Twin Disc Rigid Organic
