Nice job!

Here a couple of things I noticed and that are maybe worth a discussion:

The new tune has a positive LTFT average of 3.55. If cell 22 is = 0 at WOT it confirms my opinion that not all cells have to be negative for having zero correction under PE.

The new duty cycle is less than the older, is it because of bigger injectors or because the WI allows a leaner mix?

The difference between O2B1S1 and O2B2S1 at WOT is about 20 mV (your tune). I have exactly the same difference at WOT but my LTFT at part throttle are pretty close. Is it ok?

The PE timing of your tune is lower than before (26.59 vs. 29.46). I was thinking the added power was because of more timing which is possible using water injection. Am I looking at the right numbers or is there another explanation?

The max G/Cyl in your tune is lower that before and you are getting more power! Is it right or only the result of a new MAF calibration?

I’m not trying to rob your tuning strategy, just want to understand a couple of things ;-)
