Hey man. I don't have an answer to your question, but I see you posted it in the right place and our resident tech, Randy (RamTech) should be able to help you out with that, he's Chrysler certified. I see he's online now, so he should get back to you shortly, but good luck with that!
Great thanks for the message, i can't seem to find an answer for the average compression ratio to the 2nd gen 5.9's. Do you know it? I'm speculating a 2000 1500 5.9 but the milage is 210k and the comp. ratio's are 110-135 throughout. seems low but owner say's its average.
