I currently have a 6AT 2010 125i that already has an ECU flash from another tuning company but it is still too conservative. I dont mind having poor fuel economy for this tune if I can just flash it back to the previous map if I dont require max performance.

A few weeks ago on a Dyno Dynamics machine my car made 146.5rwkw (196hp). On the same day a stock 6MT 130i made 156rwkw (210hp).

As you can see the air:fuel ratio looks pretty conservative and I am sure more power could be had if you could get more fuel in.

I will contact the distributor in Australia and see what they can organize.
I will test the affects the adjusting the fuelling on our test car and report back if there is any benefit. Obviously you would lose some economy and as the stock fuelling curve is biased towards fuel economy.
