M2 putting down 280whp : /

Putting on flame suit. Load base dyno reveals M2 putting down 280 at the wheels with ignition timing be pulled at around 4800 RPM. That's almost as bad as my N55 F10 untuned.
The sensation of feeling fast is the 360ftlbs of torque at 2200rpm.

Not to worry though a good tune will get you out of this situation.

You can probably find a few comments in the 5+ pages thread about it from a few days ago...

Repost. This dyno run was proven invalid, BTW.

It did seem weird. In the video the guy running the dyno said 300whp and then at the end the reviewer said 280. N55's are proven to put down 280 stock. Something to keep in mind a load based dyno is completely different from a dyno jet. Also 91 Oct could of played a factor.

Link me I can't find it. Also, not to fret any tune is going to fix that problem.

That run's power peak was too low RPM 4900 for a N55B30T0, therefore you can throw it out. Yes 93 vs 91 octane can make a few hp difference.
