Not everyone here needs to pay someone to tune their car. There are several TR members that I know of that can put a laptop in their car, look at their A/F and/or knock maps and tweak their injection maps as needed to PERFECTLY tune their car.
That sure beats tearing apart your carb to change jets and power valves and adjusting metering rods, adjusting screws and stinking like gas and it MAYBE working out right.
Other people 'needing a new tune' for their carbs helped pay my expenses for years. Between holleys, edelbrocks, mikunis, webbers and other types of carbs on a variety of cars and motorcycles I have rejetted and adjusted hundreds of carbs in my lifetime (my old celica had a four barrel holley that I fucked with way too often too). Its an inexact science that is senseless to engage in if there is an EFI or MFI equivalent out there.
With the great aftermarket EFI systems there are out there there is nothing to keep someone from buying any performance manifold they want and machining and welding on some injector bosses and hooking up some big injectors and fuel rails to get any kind of crazy power they want.
You could easily take a manifold like scott's and add eight 1200 cc/min injectors to the runners which could support over 1500 HP if the manifold could ever flow that much air.
Anything you can do with carbs you can do with off the shelf components and injectors much better.
While I get a kick out of scott trying to make a carb work on his turbo project at the same time I feel like he is seriously reducing the potential of his project.
