noticed that the compression ratio of both Oz and 'other' is 7.7:1 but the other has a higher psi reading for comp test. 127 v 141. Camshafts are different between the two according to their 'binary' marking system. Can the slight cam difference be all it is , or is it also larger hole at top of turbo up pipe?

Probably the cams.
Cam open for longer -> less time to compress air
I dunno, thats just a guess
