The air fuel ratio is the green line taken at the tail pipe.

Post-tune AFR is very rich; much richer than necessary for peak power. Any idea why?

We are keeping it nice and safe with the added boost and additional heat we are making. We also have wonderful 91 Octane gas that we get to use in California, which doesn't help at all.

It is true that every other tune that we have seen pushes the envelope to make power but we wanted to avoid that. We approached the ECU tuning a little differently and think that being safe is the most important attribute of a tune. Why wouldn't we run it on the safer side for now, our tunes are already making more power than any of the other tunes that are on cars we have seen on our dyno. These other tunes are pushing the cars engine much harder?

We have our own car that we push the limits with, this dyno chart is from a customers car. We are already developing a tune on our 991.2 turbo and we should be done with that by the end of the week.
