OK, i am going to be getting the CCA 189-423-13 cam and phaser kit for my truck.

I am curious what should my settings be for the cam phasing section be?

Or just leave them blank?

Latest news.

I looked at the escalade tune and noticed a slight increase in AFM timing vs the main table. So i mimiced it on mine. I have noticed a stronger pull in afm mode with even a higher speed in afm. But i am still curious to know if anyone else pioneered this. I have noticed a sound when in afm but now it sounds stock. There is a slight increase in rpm but nuttin drastic. I will be installin a 4" maf and see it it helps with the AFM mode.

see tune for reference

Still messin with the timing

At one point i had 9 degrees of knock just in AFM mode. I dropped the timing by 1 degree and i am seeing only 6 degrees at 1400-1600rpm.

I need to keep the timing up for the truck doesnt have enough power to keep it in 4cyl mode at 100kph and 1500rpm. If i keep the timing up i get knock, but it holds. Lower the timing i get less knock but it doesnt stay in 4cyl mode.

This is a problem...
