I see a lot of ECU reprograms offered by companies, but does anyone do the same but have it tuned on the dyno so its custom for the car?

Good question!! Kinda funny how the tuners for these cars seem to have the one-size-fits-all approach to tuning.

Yeah my Evo is custom dyno tuned and its all the better for it. The engine runs so well.

Dynamic Chip...One day settings and testing...but with E55 you need a very experienced Chip or Mercs tuner to make the car not only run better but to be still reliable.

Too much boost could cause too much engine problems...
