Cam installed off a tooth? 30* of timing

[SK360]

Heres the deal, I have a 2005 GTO automatic with full exhaust, built trans and 3200 stall, we put a 228/232 .588/.595 114lsa cam in it last week and I have been working on tuning it...

Took it out to a 1/8th mile track rental today and ran with my buddy who has a 06 GTO with underdrive pulley and stall.. stock everything else

Me and him were trapping identical all day long, between 83-85 in the 1/8th mile.

I threw some timing at the car.... and then threw some more.... I was running 30* at WOT with no hint of KR...

I did a highway pull with him after, 60mph-130mph and I put a half fender if that on him.

Something does not seem right here, WOT AFR was between 12.5 and 12.8 on the wideband and no KR anywhere even with 30* of WOT timing.

Could the cam be advanced/retarded one tooth? I don't get it

It's possible.
Ever have it on the dyno to see the shapes of the power curve?
You could just pull a valve cover, and rocker set, then check the ICL on the cam without pulling everything apart.
You could just be throwing so much timing at it that your loosing power.
