CP3 pump fuel recurve

I'm looking for the cheapest pump and kit to replace my cp4. I keep seeing non tune and tune needed or recalibrated. What is this all about? Can I just buy a pump and a conversion kit and will it work or is there more to it?

If you are staying stock you need a emission compliant pump, to run non compliant pump you need a tune.

Is a stock LBZ cp3 pump considered no compliant? Do you know anybody who I can ship my computer to for a tune? I sold my EFI live with my other truck...

Check out S&S diesel. They have a conversion kit that will work on completely stock emissions in tact trucks with no tuning required.
