    Followed a few posts on the forum that suggested a Relative Compression test. Got the test done along with a parked regent on a friends computer. Trying to buy this truck.

    Can anyone interpret this?

    More research shows that the 100 cylinder is the highest with the others within 10% that seems to be within spec
