Hello

I've installed AEB large port head on AMK block. Car is stock S3.
Now i have 10% less power and about 100C higher EGT.

Timing crank-cams checking twice, and is ok.

What maps should I modify?

Thanks!

After doing some test I found: the answer is KFZW/2.

Added 6deg advanced timing,  EGT reduced about 100, and power is back.

So another question, how can I find corrected values KFZW without having a dyno?

Drive and log the car, and monitor cf values, trying to get them to around 1-3 will be a good starting point.
