I installed an MT 434 big bore today. I am currently trying to get the cam chain tensioned with the MCCT. Every time I try turning the engine, the chain goes from moderately loose to very tight with no adjustment of the CCT. Any ideas? Is my cam chain really stretched?

I started out from TDC when I installed the CCT.

with the piston at tdc and the cam timing set correctly you turn the adjuster in on the MCCT just till you cannot wiggle the chain on the intake cam sprocket.

So I am assuming that it tightened up due to the camshafts wanting to turn in opposite directions at some point after TDC?

And when you say "till you cannot wiggle the chain on the intake cam sprocket." do you mean no slack in the chain between the two sprockets?
