So, I feel like I can get more out of my tune than I have right now, but that can be discussed further along in the thread.
Right now, I am having a couple of things that bother me with driving the truck. The first is that when I am in gear and rev to a high RPM, then as it falls back down to idle, it has a hard time regulating the idle. Sometimes (if I rev too high) it will actually stall coming back down to idle.
Secondly, it does this every time when I have the A/C on. I have played with the idle air tables like crazy. My VE is in line. This leads me to believe it could be something with the timing.
I have turned off the {B4358} A/C Torque Loss Spark Correction with no difference. My mods, log, and tune are below.
