But Fuel trims are a bit high. Possible exhaust leak before the O2 sensor. I would double check your header isn’t leaking. Could clean maf sensor for good measure.
On 93 octane you should have no problem getting to and staying at IAM 1. Although depending on how you drove and how long. You may not have given it enough time. Can take a solid 10mins from start on those maps.
Also fuel trims and everything else can take a good 100+ miles to sort out off a fresh tune. Starting at .7 is to have a safe universal tune mostly for people with 91 octane. On 93 you could change it to start at .9 and have it go to 1 faster.
Based on all this I bet your car wasn’t at it’s full potential on those dynos.

Just did another quick test. Nothing major. Tried doing the "vishnu reset" to get the IAM up to 1 by steady accelerating in 3rd a few times.

Didn't budge. Then when I floored it on the way back it bumped up to .84

I feel like I'm missing something in the way it works.
