I just need someone to point me in the right place.

I want to have a throttle that is electronically opened and closed based on manifold pressure. I plan to use mega squirt to control a second set of injectors that read from a map sensor in the intake with the electronic throttle. I want to use this setup because I can keep the stock EFI system and tune and use mega squirt to provide the extra fuel that turbo charging will require.

What is the best route, what throttles can mega squirt control or what have other people used for this in the past.

Any help is appreciated.

Thank you.

I'm not understanding the point of the electronic throttle?

Sounds like you want to use megasquirt like an add-on injector controller, which is possible. You'll just need to add the injector(s), add a coolant and air temp sensor and the tach signal and map hose. That's all you need to do what you are looking to do which is add supplemental fuel above boost.

However, keep in mind that N/A cars are usually far from optimal in terms of timing when it comes to boost. After all the work above you essentially are only a step or two away from full stand alone engine management - except you wouldn't have to deal with adding a second set of injector bungs.
