Default What size injector?

So far I have done the following mods to my 04 a4 gto: PRC 220cc 5.3L Stage 2.5 Cylinder heads, TSP 224R Camshaft .581/.581 112LSA, F.A.S.T. 92MM Intake Manifold, PTM 92MM Throttle Body, SLP Loudmouth I, Kooks Long Tube Headers 1 7/8, Kooks Mid Pipes w/Catalytic Converters, and a K&N FIPK Cold Air Intake. Right now the car has 400hp/380tq at the rear wheels. I used the search engine, but couldn't find out what was best for my application. Can anyone help me out with chosing the proper injector?

36#er's would most likely suffice, 42#er's if you plan on growing in the future (who doesn't?)

Is the a particular brand of injector that I should purchase? I thought about purchasing the FAST fuel injectors, but I just wanted to make sure that there isn't a better injector out there that I could get for the money.

A 36# would be perfect. If you have any questions or if you are looking to pick some up, shoot me a pm or give me a call and I'll help you out.

I bought 42# Bosch injectors, flow matched, and they drop right in and are supposedly easy to tune.
