Looking at the % increase on each 'run'

1 6.6%

2 11.02%

3 14.36%

Significant increases as the unit conditioned. It should be fair to say in this case that the emissions figures quoted, being averages, should be significantly better if the last run in isolation was used. I would like to see the full report and do some analysis, the results are good but it looks to me that even better results are held within the report, taking SAE J1321 math out of the equation, excuse the non-intended pun.

And BTW, nice post smrtinvester. Welcome aboard, hopefully you have arrived just in time to see DYA hit the SP that we all know its worth.

GLTA.
