I was just checking out the F-Max web page. I have a question about the dyno charts for the 200sx ser. The first chart shows max power of 262.7, the 2nd shows 291.2. I'm assuming that this is whp, correct me if I'm wrong. My question is, what was done differently between the two pulls? I noticed that the temperature changed from 82.7F to 79F and 29.86-0.44 Hq CF= 1.00, changed to 29.92-0.44 CF= 0.99. Besides the temp, what do these numbers mean? It is the air:fuel info? How does that work? Could someone break it down in the simplest terms possible?:)

Here's the link to where I was looking:

One's open loop one's closed (fmax terms for wastegate venting to atmosphere or recirc into downpipe)? Might be a possibility...

One was at 10 psi without water injection, one was at 14 psi with water injection.
