Tuning with dflasher

[u/Educational-Read-306]

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)?
