I just got done wheelin' with those guys at the chili challenge and i can honestly say that his set up is sweet. If you think about it, converting to fuel injection isn't all that cheep, unless you know where and or whom to get the setup from cheeply. I remember him tellling me that you can wheel for a few loooong day with a small tank. Also, couldn't you just flip the propane on and inject it only when you needed it? His truck sounded cool as all hell when he wound up the turbo..here is a pic from Habenero Falls
