Hi Jonny,
I couldn't agree with you more. If you have a Qjet and HEI that work well for you, or budget is a major consideration and the enhanced drive is not important, stay with what you have. If you have a less than good carb or distributor the change will likely be more than enough to justify the cost.
This FiTech EFI offers a large matrix computer based self learning process and lots of manual input for spark control with a two wire locked out distributor if you want to quest after the bleeding edge of mileage or performance. I am not interested in anything but a reliable, nice to drive GMC experience without any drama or tinkering.
Without a factory engineered knock sensor system and very accurate exhaust gas temp sensors that work 100% of the time I would not want to take A/F ratios up very much, or over advance very far during lean cruise, in a quest for a small increase in MPG. But, that is just me. Sharon and I measure our time in our two GMCs by smiles per mile far more than miles per gallon, but we both enjoy the vastly improved drive experience offered by these self learning EFI units. bTW, tonight we just enjoyed a thrilling sun set at Picacho Peak State Park about 50 miles from Tucson, AZ. Life doesn't get much better than this......
Where we all drive has far more to do with mileage than anything in the technology from what I have been able to determine. If you drive in the flat areas of the country mileage will be higher than for those of us who drive in the mountain west. If you drive slower mileage will be higher. If you have a lighter coach mileage will be higher. If you drive more smoothly and accelerate more slowly mileage will be higher. If you drive with higher vacuum your mileage will be higher. Etc.

Well, I do about 9 towing and about ten bobtailed in my 23' with a really scurvy looking Q-jet which I kind of think is the original. Alls I've done
is tighten the mounting bolts and the screws that hold the air horn on, thereby stopping the fuel weeping. It looks like it does about 6K miles a
year. At $2 gasoline, an increase from 10 to 11 would save me $110 a year. Even the FiTech doesn't pay out, JimK's fancy one doesn't either. At
engine build, it might be a thought. Right now, me and the Q-jet will continue to negotiate.
