Not only that......

Notice that your fuel trims dive to zero in the first two logs.

We are seeing an awful lot of that erratic behaviour with these aggressive maps.

But I am seeing too much of this lately to believe everyone's injectors or O2 sensors are going bad at the same time.

If I were you, I would log your AF ratios instead of fuel correction since fuel trims are directly impacted by your AF ratios.

I would also increase you OL fuel higher than 75 with RB turbos since you are moving a lot more air and will need more supporting fuel.

Your other choice is to go back to earlier maps and see if the problem with timing and trims clears up.

I think some members have tried the 7-29 maps.
