Although not the cheapest, it's probably the best mod you can do to your truck. We installed efi on 2 trucks in a little over an hour. And it was our first time doing it. We spent more time trying to figure out where to mount the switch than anything else. Thanks to Willie and Kory, any issues we've had have been resolved super fast. I'm sure he will chime in, but you might PM mrmanners(Willie). Kory Willis has got some great tunes and very clean.
Buy EFI Live, not a hard install, I personally would get tuning from either Idaho Rob at ATPTrucks.com or Kory Willis at Synthetic Motorsports.
