Save the .CSV as a .txt and then attach it. Also, you can use VD: http://www.bradbarnhill.com/projects/VirtualDyno/ to graph it really easily

You're having timing corrections across all six cylinders, sometimes 4 cylinders at a time. That will definitely explain the "off" feeling.

What map are you running? Stage 1+ aggressive?

cobb stg2+ agg. im FBO. 93 oct. could this be gas station related?

Try a different gas station. I try to stick to authorized Top Tier gas retailers (http://www.toptiergas.com/retailers.html)

My personal preference:

Shell
Exxon/Mobil
Sunoco

It definitely could be. That would be an easy thing to test/fix.

Yep, that cleaned up the timing corrections very nicely.
