In the original dyno the E90 read 12/13 AFR as you would expect, I assume the whp delta is due to o2 sensor

Anyway, sometime this season I'll dynojet it again.
...or it could be that Jordan's dyno is a little happy? I've seen/heard of a few guys that dyno'd elsewhere on DJ's and recorded lower numbers. I've seen some pretty wonky torque figures for S54's come off of his dyno too. SAE is typically about 2.6% lower (77* correction factor vs. 60*), so that would make it around 453 HP...still crazy power! Get that O2 changed and see if it picks up any power!
