Therefore, would me adjusting the CO2 and the TPS be satisfactory as regards the fuel mixture with the DNA Stage 2?

I installed the DNA stage 2 filter one week before I received the PC. I increased the CO from +8 to +50 (first tested the bike with +40) and the bike worked quite well. In fact, the stage 2 filter seemed to increase the power a lot at low and mid revs ( http://www.xt660.com/showthread.php?t=661)
After installing the PC I noticed another equivalent power increase to the one obtained with the stage 2 filter but I could have also lived without the PC.
In my case, increasing the TPS value made the bike work really bad (tested it before installing the PC)
Just my 2 cents
