Actually to be honest, all of us powerstrokers hate the EFI...each injector is 250 bucks...LOL But they do make for easy mods, i mean I did a downpipe, and reprogrammed my PCM with a superchips plug in to have an instantaneous 300hp and 600 ft lbs...self tuning can be fun, but when a cam sensor goes south on the interstate, or rather at the front gate of base *cough* leaving the truck stuck for a second to reset, one likes the mnechanical setups. I wish my truck had a cummins, but it would be slower.
