Tuning is being handled by Technique Tuning whose owner is the only person to have a successful turbo kit for E46's thus far tuned on the stock DME. NickG as he is known has produced kits for M54 based vehicles and is arguably the best tuner to make this S54 kit happen on the stock DME. It is not easy as many tuners have failed attempting to do the same.
Dyno is on 93 octane fuel. Turbo is a Precision 6266CEA.
This is an absolutely incredible development for the S54 market and if NickG and Maximum PSI pull this off, major respect from the BMW tuning community is warranted. Good luck to all involved! Pictures below.
