First off would like to say hello, i am new to the forums and new to audi but not to the car scene, i own a 99 audi a4 1.8t 5spd with upgrades internals " ie: pistons rods etc." ""AEB heads(correct me if im wrong) haha "garret gt35r turbo. custom exhaust manifold , custom down pipe into a complete custom supra exhaust. vr6 maf , s4 injectors, lowering springs and other odds and ends. but onto my questions.. i am looking to get larger injectors what size should i go with? and i really need to find a tunable ecu that i can pick up install and send over to my dyno guy.

so all in all my 2 questions to anyone on here that can help me are.

1: what size injectors should i go with.
2: what ecu is best for my set-up.

any help is greatly appreciated!
