Thanks yfin. I'm not too hung up on it now anyway. But still plan to repeat the tests on another dyno.

I know ambient outside the workshop was 30C+ yesterday, it was only a few cooler inside. I'd say there was probably about a 5-4degC difference between my baseline run a few weeks ago and these yesterday. I think from looking at the bottom of the graph it indicates that ambient temp was 25C, intake temp was 30C, relative humidity was 60%, and barometric pressure was 101.3

Those values almost sound like ideal's for the software and calibration, not actuals. But I may be wrong...it felt worse than that.

I've had the intake installed for almost 4 weeks now, all the time running the BMC filter (with and without drycharger). So the ECU may've had to adapt a little to the filter change between runs, but I imagine that'd be of negligable effect.

I'd planned on doing before and after acceleration tests, but due to the inability of the installer to install the RSM+G-Sensor I installed the CAI first, then a week after that I installed the RSM myself. So I might go get some more acceleration figures tonight which will be with the K&N filter.

Yeah I'm not to sure about the air to fuel ratio either. :scratchhead:
