VCT & Performance Impact
At startup the VCT is locked at full advance.
It can retard the cams 0~55 degrees.
The more retard the more EGR.
VCT is part of the emission system.
Now 'most' of us feel more power with a cold engine. As we take off with a cold engine it feels like the truck has more power; the more advance at low RPM the more TQ.
You can also google advance/retard camshafts and find the performance/driveability impacts
Just FYI.

the reason you fell more power at start is cool combustion chambers. these 3v's burn hot enough where porters don't remove much material from the chambers to avoid burning the heads out.
3v's can hardly be made to run cool even with bigger radiators and t-stats.

The stock programming retards the cams 30-50 degrees in the low range.
You are locked at 0 degrees VCT advance w/ 8 degrees retard. Now in my tables for the VCT if i set it all to "8" i would be exactly where you are at, where you also said you gained power from it correct?
