Guess that answer the question of the N55 being un-flashable... Great news as far as I'm concerned, and pretty decent numbers to boot..

Always a critic. j/k... I think if it had been titled 1ST FLASHED N55 with DYNO might have gotten a better reception, but it's still good news, even with a mangled title...

OP, was this flash done through the OBD2 port or did they physically remove your ECU/DME to bench-flash it?

Good progress for the N55. Are they able to reduce the dropoff after 5500RPM though?

It all depends on what boost they ran up top. As for fuel they need to richer it during spool. That's a different table in the Ecu. It still needs work, however its better than the other tunes.
