    To me I always considered bolt ons stuff you could do fairly quick, with basic hand tools and little to no experience turning wrenches.

    To me then it isn't "full". I realize it's off topic to the 7.3 swap discussion, but FBO drives me absolutely bonkers. "Full" absolutely implies everything. If you only did nothing burger changes like a CAI, just say you did a CAI rather than using a vague phrase that sounds as though you might have made a change that impacts power significantly such as heads, cams, stroker kit, turbo, etc.

    I agree, what I was commenting on was the debate over what some people consider bolt ons.

    A supercharger is pretty easy to bolt on.

    FBO to me means leaving the long block, transmission, and differential intact.

    A tuner/programmer is a required part for modification. Even without a tune, the units are $400.

    I've always this considered part of the tune, and this would be required for any vehicle or engine.

    But again, I would go with a stand alone EFI managment for the 7.3L for any type of retrofitting.

    Then you are talking more than $1000 for the equipment alone. Programmers are only required when modding.

    Stand alone systems can be had for ~ $1000 or less...all wiring included. For any type of retrofitting, this is the way to go. Even LS1 stand alones cost more or less the same. All of these systems self learn...and there is no need for any dyno time or mail order tune costs.

    This doesn't change engine costs though. And again, I'm not talking about taking out a coyote and swapping in a 7.3L.

    Swapping in a 7.3 for any application and adding bolt-on mods will require a programmer, if you don't go the standalone route.
    In regards to the standalone (like the Holley unit), their self-learning leaves a lot to be desired. My friend has the Holley system on the twin turbo LSX he installed in his boat. It has never really run quite right, and is going to have to be tuned. If you want to really get the most out of those, you will need to hit a dyno. I would stick with a SCT or n-gauge if I wasn't fairly experienced in tuning.

    I have used self learning Fitech. It worked amazingly well. Stupid easy to set up. Stupid easy to learn. My 427 with a fairly lopey cam had no issues idling.

    And no, you don't need to hit a dyno. WOT self learning can be done on the street or at the track. Tunes come in conservative. You input your engine size, cam size, N/A or FI and it throws in conservative tables....enough to get the engine started and running.

    I've used these. I know others that have used these. They work very....very....very well. Holley's are setup very much the same way....almost scary close to the Fitech.

    Those that have problems, they are nearly 100% of the time attributed to poor grounds, poor crank/cam pickup signals or vacuum leaks.

    there are already a good handful of shops that build 427 from the Coyote platform (boss crank, blocks, heads)
