I have a 98 12 valve engine harness and computer if you are interested I used it for my 01 ram 1500 cummins conversion but totaled my truck. If you are interested in it shoot me a pm.

Thanks for the offer, but I am up & running. So as the old addage goes: If it ain't broke, don't fix it. Now I just have to figure out how to turn her up. I hear that the fuel pump can be dialed up & adjusting the wastegate will help (if done correctly). Looks like I have a bit of homework to do now.

How much do you want for the harness and computer i need one :tu:

Sorry bud, I sold the whole drivetrain, lock-stock-&-barrel.
