You need to clean up your channels list a lot. You have a lot of duplicate and unnecessary parameters that are just taking up bandwidth. From what I can tell it looks ok, but I highly recommend logging B1 and B2 O2 sensor voltages, they are very helpful to see what is going on in each bank.
If you are interested, I offer email tuning with hptuners and/or guidance to help you tune if you are looking for outside help.

I do need to cleanup the channel list for sure. I thought I had o2s on there I guess not I'm pretty new to this just got the afr hook up to hp tuners. my Ballenger was showing super rich like 9.2 at wot. On the scanner it looked fine that's all I was concerned with on this run. This tune is a dyno tune. I was seeing 20.6 max psi minus 1 bar I believe is 6 psi correct me if I'm wrong?

Depending on your elevation normal air pressure is 101kpa = 14.7psi = 1 bar. So yea 20.6-14.7=5.9psi. Similar way with MAP, (126/101)*14.7-14.7=3.6psi.
Always believe what your gauge says, then make the scanner match the gauge. If the gauge shows AFR of 9 and the scanner laptop shows 11, your scanner is wrong and needs to be fixed. During cruise with closed loop it should bounce around between 14 and 15.
