So the boost pressure was 8PSI,
Fuel ratio was 11,03 /11,17 on read line
Fuel grade 95 AKI
So the mechanics ask me if it's possible to set little beat lean,around 11,79 ,and remanning on safety zone?
So they believe around 11,79 a car may push more HORSE power.

520whp on a dynojet is about what you should be making on a 625 kit. You're not going to be able to lean out your car without a re-flash. Target AFRs are around 12 to 12.5:1; you may be running richer because its so hot and the DME is targeting richer AFR for that reason.
