If all cylinders were right equal at 100, I wouldnt worry about it, all is good. The main thing is that they are equal. Decarb may bring it up a little, but alot of the V6 Johnny Rudes arent going to get 160 psi by any means.

Sounds like a decent motor from what you have stated in your post.

The V6's don't run high compression , anything around 80psi and up is fine.

The 2004 should be a FI engine and 100psi is ok as your guage could be reading low(their all equal). I would have it checked with a laptop/software to see how many hours are on engine and what rpm range it was most operated at.
