The problem will be with getting the computer to function properly with the larger throttle body. It isn't as easy as the old carburaters. Everything on a computererized engine is carefully matched and balanced.

There are a couple things that you might be able to get by with to increase power a little without a complete computer system replacement, for example, you might be able to put on headers, increase the compression by no more than one point and go to a SLIGHTLY more aggressive camshaft. Anything beyond that will cause problems, but be careful with the camshaft, that can be trickey.

Throttle body injection has one injector located in the throttle body that supplies fuel to the intake manifold. This fuel flows to all cylinders just like it does on a vehicle with a carburetor.

Why is port fuel injection better than throttle body injection?

Because the port fuel injection sprays the fuel right onto the back of each intake valve. This means each cylinder is getting the exact same amount of fuel as the rest which helps with fuel efficiency and the amount of power created. Whereas the TBI (throttle body injection) has only one or two large fuel injectors spraying down through the throttle plate and into the intake manifold. Then the fuel just kinda gets sucked into each cylinder and usually goes for the cylinder that is creating the most vacuum.
