What is selling you on wanting to go throttle body?

Don't let the self tuning marketing steer you.

Go with a carb or port EFI. The tuning is not difficult, its easier than fine tuning a carburetor that is for sure.

The bonus of going to fuel injection is that with the right system you get a fuel controller, an ignition controller, and a Datalogger all in one package.

I started with no EFI expierience and I have a few thousand miles on my EFI setup now and I would never go back.

Just like you can find people with crappy carb tunes you can find people with bad EFI tunes as well.
