Laptop tuning is not hard at all once you understand it. For instance, a few weeks ago I tuned a 02 6 speed Camaro with 42lb injectors, big cam and bolt ons in less than 3 hours. At the same time we tuned his buddies C5 vette with similar mods but an automatic. Most the time was eaten up driving around from here to there dataloging and making some minor adjustments. Both cars ran stellar after that, all with out getting dirty and in 3 hours
Anyone that really dials in a carb spends at least 2 hours swapping parts and playing with the thing, but getting dirty
Carbs have there place, and so does EFI. Heck, my little 347ci motor ran incredably well with a 243/250 @ .050 cam, single plain with a dominator throttle body. A computer will never get it perfect because it lacks feel. Just because a wideband says it's perfect doesn't mean it is.
