You starved for fuel from the top of first gear through most of 2nd gear, starved bad. Its WAY lean there. This was due to the fuel level/supply.

There is alot of bouncing around for AFR and AFR error, with many points more than you really want to see, especially at WOT. I would dial this in manually myself. From looking at the logs I would say the engine was breaking up from 3600 RPM in 1st gear pretty much through the entire run. This could be something with the sensors you are using, but RPM should not be decreasing from point to point during a WOT run.

You should adjust your throttle cable, you're not getting 100% WOT according to the TPS.

Are you using the sniper for timing? If so, once the fuel is sorted out you can add 2 more degrees and go from there. The engine might like anywhere from 2-8 more degrees of timing.
