Would difference injectors benefit? I have stock injectors in my 99 TA of course. My question is what difference would bigger injectors bring about? HP, MPG difference?

It would help to know what kind of duty cycles your stock injectors are running at with the amount of power you have. Chances are they're running pretty close to static. I don't know if you will see much of a noticeable increase in mpg. On my last tank (the first since I upgraded) I gained 1.4 mpg, but that could be due to a number of other factors as well.
With the stock injectors you are probably putting an artificial ceiling on hp though. Use the injector size calculator to determine how big you need to go. Remember that the sizing calcs are based on fwhp, not rwhp, so you'll need to factor that in.
Give us some more data and your planned future mods and we can better help you.

Injectors don't give you any horsepower or efficiency. If you don't have enough injector for your engine then your engine will go lean and lose power and possibly sustain damage when it runs out of fuel.
