Ok, that makes sense then, i get it!
You leaned out the top just slightly, why?

It was a bit rich on my wideband up top, the way my modifiers are setup now, It starts around 12.6 and the tapers up to about 12.9 or 13.0 on the top end. It made more power up top a bit leaner, but the fatter mixture in the midrange helped supress the KR I believe.

Am I safe copying your values? I have no WB on the envoy to verify afr.

Cool vid, looks like it moves out pretty good.

Yeah, because we havent done anything to mess with the VE of the motor, so the PE values are pretty accurate. I just think GM made it leaner to help economy. Kind of like the high PE bypass rpm and TPS bypass.

Cool. Thanks again for the tips and all. I appreciate it. I'll give it a go and see how that helps with the kr and performance.

Again, my stock "Base Angle (PE)" in the Variable Camshaft section matches yours exactly. What does adjusting this table do and what are the results of yor adjustments?

Good. Should these values be adjusted lower too?

Iwould set the bypass points lower, and as for the cam setting, I felt difference in the low and mid range, very minimal change up top. Not a ton of difference but there was a little with changing the cam settings. Making the cam numbers lower is advancing the Exhaust cam.
