05 mustang 4.6 3v question on IVO
Hey guys,
I just installed some hot rod cams in my mustang and got it idling pretty good, but power seems down up top. I have just updated the VCT tables per their directions which would retard the cams 20* at wot. My question is in regards to the IVO, the spec on the cam card is 49 degrees BTDC which would be 311 degrees. Now since I am retarding the cams With the VCT 20 degrees do I need to change the IVO to 331 to compensate for this? Or Will the pcm adjust for this?
Thanks!

I?ve been running it at 311 and everything seems ok. I ran it at 331 and didn?t really notice a difference so I changed it back.
