On the A/F, I haven't set mine up yet for that, but anytime you are in "Closed loop" the MAF and 02's will make every attempt to keep fueling in the stochiometric range of 14.7. You'll see that number bounce around a lot as small sampling corrections are made. These can also be seen in the short term fuel corrections if you've set it up to read them. Go WOT (Open loop) and you will see the true A/F tuning. Ideal will be around 12.5 but chances are it will be richer than that (lower number). You can also set the scan gauge to indicate when it goes from Closed to Open loop

Thanks for the feedback modshack. A/F ratio looks to be steady at about 14.5 but Long term fuel correction is around -5 same for short term fuel correction. I am no expert, but take that this means I am still running rich. I can also hear it, there always is a nice popping in the exhaust when I shift down at higher RPM.
I wonder if Takeda will ever come out with the heat shields that they promised Amplified. I guess we'll have to wait until after SEMA...
But I will most likely change to Stillen G3 after this winter anyway
