I don't have any problems tuning a carb setting dwell or timing. air, fuel, spark in the right sequence and amount, been doing it for 35 years. My reasoning is the factor of having something way cool, a 68 charger with a fuel injected six pack, with the market getting younger and younger there's only a hand full of people that will be able to tune these cars in 10 or 20 years, this just increases the desirability of the car to the new generations. has anyone tried to buy an original six pack set up lately? (I know mine didn't come with one but my car is not original and has been way molested, threw the old wiring away too, no more ballast resistor, and one wire alternator, nice bright lights, and no smoking wires.) the fi-tech set up is right there in pricing. for the unit, a tanks inc tank with fuel pump, and sending unit. probillet distributor, coil, and module, initial set, tech support from norm in oxford, Michigan, 1 1/2 hr away drive. (very knowledgeable and personable guy) $2800.00. I just bought it, be here in two weeks. there's a six pack set on here for $3000.00 so I feel I got an electric fuel pump distributor set up and a tank for free.
