There is definitely more to come but so far early on Maximum PSI and Technique Tuning are showing the ability to tune built motor S54 setups on the stock DME which nobody has successfully done. Yes, it's not easy.
The second graph shows Maximum PSI hitting ~18 psi of boost on pump gas for 660.8 wheel horsepower. It will be interesting to see the Stage III on a Dynojet. Keep in mind, with dropped compression on a built motor one generally will make less power per pound of boost than at the OEM compression ratio.
The turbocharger used is a Precision 6466. The fuel is MS109 for the first graph and pump gas for the second graph. The exhaust system is a 3.5 inch design that is catless.
BimmerBoost will of course be watching closely but this is a great start.
