I would consult your tuner and let him see the log and explain why the parameters are the way they are.

I will question about the lambda values. I've emailed APR about the boost levels prior to data logging, they were pretty on point saying max 1.4 bar and tapering off to 1.1 bar.

A boost leak or something else?

I tried looking for the setpoint boost pressure but didn't see it. Is it an available field with the 6.2 software?

Using data from your first post. Looks pretty good to me.

Is that the boost? Looks like a normal taper.

Thanks everyone for their help so far!

No man, that's load vs rpm. Greater load = greater torque. You should put in some race gas and load up that 100 octane file. I'd be curious to see what your load curve looks like.

Gotcha. I'll be doing some logging with 100 octane soon, just have to finish the 93 in the tank now.
