To the OP, what power do you want? Stage 2/3 T3 is relatively cheap and very easy to install. If budget is less of a concern then I would be looking at the GT or GTX range as mentioned.
Many thanks!
The richness I am aware of, although it does begin to lean off after 6kRPM;a certain Derby based outfit reckon the injection system is dealing with more than it can handle, even with the 5th injector. It's one reason why I am considering going to a modern EFI setup, maybe one of yours

It's good to see the GTX ranges being mentioned, it will be something to potentially look into in the future
