ESS HP bump with exhaust?

Hey guys,

I have X6M with Hamann (supersprint) rear section exhausts.

I was wondering how much hp does ESS direct flash unit would add to the stock 555hp with the hamann rear section?

I also had the hamann ECU upgrade which pushed it to 610hp but after each BMW service, the ecu gets reseted and the power goes to stock so i would have to send the ecu all the way back to germany each time after service to remap the ecu to 610hp.

with direct flash, it seems like i can do it myself after every service.

btw, i also use 98 petrol and sometimes 100 shell.

Thanks
