What is the best AFR for a 3SGE Beams with ITB Throttles.

Hi there. What is the best AFR for a 3SGE Beams with ITB Throttles. I have attached my tune and my logfile. The log file is long from a drive yesterday but the last 10 mins of the drive would be good to look at. The engine is stock except for the ITBs and headers and a free flowing exhaust. I am measuring it with a Link Canlambda at the front in the 4 into 1 collector. My fuel tune is with TPS on one axis on the table and and RPM on the other. The car is running nice. 

At the moment I am targeting the below:

Between 1% - 7% TPS, I target lambda 1.

Between 11% - 25% TPS I target Lambda 0.96

Between 25% - 60% TPS I target Lambda  0.96

Between 60% - 80% TPS I target Lambda 0.85

Between 80% - 100 TPS I target Lambda 0.82

The car get driven on the road but also does get leaned on a certain amount.

 

Any thoughts  would be appreciated.

Here is a link to my tune file and my log file.

Something like below is what I would use for an engine like that.
