ESS flash for N55 335i (with dyno chart)

Car spec:
2011 335i Sedan with M-sport pack.

I live a 2 hour drive away from ESS headquarters in Norway. I turned in my car on a Sunday and picked it up Saturday the following week. The ECU had to be removed in order to do the flash.

I chose ESS flash because of the solid reputation of the company, also my own personal preference is flash over piggy. Customer service was great and Im very happy with the result. Car picks up from down low and feels really strong at any given RPM.

Flash was done with 93 octane gas (98 in Euro-terms) in the tank and redline was raised to 7200rpm.
I have no hardware mods yet, the Dyno result is only software Stage 1.

Any idea how much boost your flash is running? Also, what is the benefit of raising the redline to 7200 rpm if you are manual? The power curve really continues to fall sharply at 7200...

thanks guys. Im not really sure why the higher redline, im never in that area anyway, i guess it just sounds cool when i say that my redline is 7200

As far as the gains, its what i expected from the flash, i have no idea what boost im running, most likely 15psi?
