Lots of kits on the market these days, BUT you will pucker at the cost. Good kits with Bosch wideband are around $500 or so. It's a big hit at first but totally invaluable for engine monitoring and tuning. I have seen some lower priced kits around $350 or so.
Just need to decide if you or someone else will tune the beast. Going with Nelson and others would probably negate the need.

 

Seems STs or radix is the way to go.

 

I got a PLX Devices M300 on eBay for a great price. It can hook into the DIY tuning software (HPT, EFILive, etc), or a stand alone computer setup (megasquirt, etc). I paid $313.

You really can't go wrong adding this to your truck -- it may seem like a lot of money, but the peace of mind is worth it -- instant in cab feedback about your fuel system status.
