Fuel and spark

We are currently piecing together a turbo kit for my partners 97 ram. Its a 5.2 magnum. So far on the list is, Holset HX35, diesel ram intercooler, custom headers, all hot and cold piping, vacum pump for power brakes, maybe a boost sensitive fuel pressure reg, and oil lines.

This is purely for more towing capacity. I’m having a hard time coming up with what to do with the computer. Does anyone know of a piggyback?
