    You need to make sure to smooth out any spikes, I would knock that massive random spike down as it's not accurate. Use ~50-100 cell hits before you start using your log data and make sure you have followed the AutoVET procedure.

    Thanks for the feedback. This was my very first run and I assumed I needed to get a higher cell hit count to be more accurate. This was derived forma 45 min drive my lowest hits were around 30 and high hits were in the 1000's. As I am sure you know the High RPM mid pressures are hard to hit. The neat part is when I look at the 5.3 chart vs the 5.7 chart and then compare to my tune my tune seems to mimic the 5.7 chart only less air intake overall. I believe this is the case since I have the LS! intake on the 5.3 motor.
