autojohn?!?,

Your "ned" needs decryption. It got hammered in transmission (usually happens in a Dodge) or something.

If I'm guessing right, you want to add power to your Mercedes/Chrysler/Cummins for very little money. I think you're knocking at the wrong door for an answer to that. Most everyone here will tell you that your only option is to get a Duramax.

Or, you can try the Dodge board. There, they will tell you that Cummins were given devine power from God, so all you got to do is start praying and you'll get more.

Other than that, I have nothing constructive to suggest. (Autojohn? Seen those in truck stops. Stand up and it makes the last supper go away.)

Guys are using the Predator on their Duramax's and upgrading their exhaust to 4" systems for about a grand. Not sure how the Cummins and Predator work together. Recommend you do a search on the internet and see what's out there.

You will need an EGT gauge, figure another $200 and you should be good to go. :ro)
