For those who have tuned with dflasher, how has your experience been? Reliability? Any issues at all?

I am looking to flash my 2009 335d with the m57.

Main reason is the ability to switch easily since it just requires an adapter and so that I can incrementally do the delete.

And for those who have tuned their m57, what numbers have you pushed on stage 1 (and stage 2 if applicable)?

I have a 2009 335d that is still relatively stock under the hood but I am getting to the point where I am going to try and do a delete soon but I want to try and break up the work.

Am I able to do the swirl flap and egr delete right now and avoid limp mode or a CEL? Or do I need to do a tune after that part of the delete?

And I definitely need to do the tune right after I do the downpipe right?

On a side note, if I notice oil in the intercooler and around the charge pipe by the turbos could that be either a bad turbo seal or bad crank case? Or could it be something else?

Any and all help is appreciated. Thank you.

Hello I am just looking for some advice since I just bought a 2009 BMW 335d (titan silber on black with wood interior) and it’s being shipped now. My goal is to keep things oem+. I probably want to eventually go stage 2 ecu and tcu. And yes I’m aware that I should do maintenance before mods and I already have stuff lined up.

1. What are some good looking apple carplay units that don’t look completely out of place and work seamlessly? If I go the carplay route I’d probably look to get a back up camera in the future as well. Or is there a good usb dongle or unit that works well and can hide away?

2. What is the best obd2 scanner/programmer that works well with this car’s computer and can handle all of the different programs?

3. What should I prioritize on an emissions delete? I probably want to install a down pipe but probably a little later down the line. I’ve heard that one thing can be coded out and then something called “… flaps” can be removed? I live in a place where they don’t do emission inspections so I just want to keep the car running as smoothly as possible

4. What tuning company should I use for an ecu tune? What company should I use for a tcu tune? At the max I would want to go stage 2 and I more than likely will start out with stage 1

5. Are there any other tools that aren’t obvious that I should have? I don’t have a torx or an e-torx set yet so I’m going to get one of those but is there anything else?

6. What are the preferred maintenance intervals for a lot of the common work? I was planning on doing oil changes between every 3k-5k miles but what about things like fuel filter, fuel injectors, glow plugs, etc. Also on fcp euro the kits show 5w-30, is that the best oil type? Is there a specific type of liqui moli that is best?

7. What brand has the best intercooler for this car? Best down pipe? Best coil overs? I’m also looking to get some apex-ish style wheels, Is there a good brand in the states? Or should I just go alibaba?

Any and all help is greatly appreciated! Thank you
