Of course for probably the same price of a set of new Webers you can fit a set of Toyota throttles, fit an ECU, have it tuned and maybe have a few bob left for a case of beer. You'll save fuel on the way to get the beer and won't have to retune when you get back.

Unless you race in a very specific formula that won't allow you to use ITB's and injection, for me there is absolutely no motivation to use carburetors anymore. None.

At least here in South Africa that's the case and carb tuners are now scarcer than hens teeth. Those that are still around are stupid expensive too.
