There is not a large sample of f10 users you can rely on that have provided solid data, and the only data I have seen has indicated there is a potential problem. If you don't have data you have no way to know what is going on inside your engine.

And I'm not talking about max power, I'm talking about having confidence that the tune you installed is SAFELY adding more power. Driving feel is only important if you can be sure you're not causing damage to your car. Without verifying myself that everything is copacetic I would not be running this tune, but maybe that's just me.
And you are basing your view on a single failed dyno testing.

I am trusting Terry Burger's years of experience and tens of thousands of proven example of success in his tuning ability. The N55 engine in our car is not a new engine. The difference in our engine and the one in say E90 335 or F30 335 is minimal.

Oh and another thing, there are Other F10 535i JB4 stage 2 dyno out there than the one you shown.

Like this one, much smoother:

Map 2 (14.5psi)- 297.98 whp (375hp crank aprox). 365.95 wtq (446tq crank aprox).
Map 1 (12.5psi)- 298.97 whp (372hp crank aprox). 347.91 wtq (424tq crank aprox).
(*Note, this guy have downpipe and exhaust. +75HP and +146lb torque over stock ... this is obviously a guy trying to shoot for most HP lol)

2011 535i Alpine White, Oyster on black interior, Premium 1 & 2 Package, Magnaflow Full Cat-back Exhaust, JB4 Stage 2
