Need advice on ko4 (i searched)

[D-rock11]

i've been googling and seachering for the past couple months, and asking all my buddies, but still need some mroe help. heres the deal...

i have/came on my b5 a4: AEB 1.8t, ko4, giac chip, upgraded side mount.

i bought: test pipe, 440cc injectors

NOW my questions:

what software can i run? i know i could get mine reflashed but i dont live near any dealers that can do it, and i didnt buy the chip myself so they will probably charge me more

what FPR do I need? i thought mine had a 5 bar, but i checked this weekend and its a 4 bar...i think it all depends on your software, but what would be a good or common choice?

would upgrading the maf help? i know its not needed, but what if i get a 3' vr6 maf? ive seen some ppl use them on otehr turbo setups, why not on a ko4?

Again im still learning alot of about turbos and what not so i apologize for the dumb/repeated questions. any help will greatly be appreciated!

Everything you asked is tune dependant. And I don't know any k04 tune for the B5 A4 platform that runs on 440cc injectors. They are simply too large for a turbo the size of our stock one. From the supporting mods you listed, you made it seem as if you have a proper running k04 setup. Is this not the case? What tune, injectors, fpr, and MAF are you currently running?
