Just FYI, I have a similar setup, and I picked up ~20 peak WHP over the TODA tune when I got mine dyno tuned.
The midrange HP and Torque pickups were amazing.

My VTEC engagement is also higher than the TODA tune due to the lack of a testpipe. I think mine is actually higher than a lot of people here, but it showed no improvement on the dyno by lowering it. We did 13+ full runs on the dyno, with a bunch of lower end runs working on VTEC and mid-range.
from where did most of that power came (AFR or timing ) ?
Both?
He made changes to both Fuel and Timing maps, so I'm not sure where most of the power came from.

I can't tell what the lower number is bit the a/f could use some work you want it to be flat and lvl around 12.8...on that note it doesn't look like any of the a/f could be super dangerious that's going to blow the motor

use external wideband for AFR because AF in the flashpro read richer . or you could use AF corr if you dont have time for a wideband . my wideband reading is very close to AF corr reading .

instead of taking a screen shot, post the actual log. to save the datalog hit datalog and save as. give it a name and upload it as an attachment to your reply on the message board.

thats strange. There must be some kind of confusion.

Didn't gernby install a wideband on his car and determine that the AF reading is closer to AF instead of the AF Corr?

AF actually read a tad richer than the WB sensor.

I know on my car, the AF corr and the AF are totally different. AF corr reading much higher than AF.

I havnt tried an aftermarket wideband yet but if I correct for 12.8 on the a/f corrected number my fuel tables look way outs wack and the WOT tables looked way rich abover everything else.....a/f looks alot better

I'm going to be starting an Evans E-Tune any day now anyway, so my current datalogs are relatively irrelevant
