Afc

[tsick]

Right now i am running ~18 psi without any engine management. Im in need of bigger injectors badly but lack the funds. By tuning with an afc and turning the boost down a few psi, will i gain more power than what i am at now with the higher boost?

we cant help you much with out your mods. Your car says just talon TSI and you dont have any mods in your profile that I could see. running 18psi in my opinion on any turbo on the 4g63 with out fuel upgrades is not a good Idea you would atleast need a fuel pump and bigger injectors. I really dont think you'll gain much more power from turning down the boost and tunning the fuel but i could be wrong why dont you just tune the fuel for what your currently running instead.

Turn down the boost.

i guess a AEM ems is outta the question, i would leave it as is until you can get some injectors. just my 2 cents

wow you did some things out of the ordinary. like getting a built engine and what not with out the BPU things that cool though your set up is nice. I would def invest in a S-AFC you can get the 1st gen ones for hella cheap now that the S-AFC II is out. Yea I would turn down the boost to 15 until you got some injectors and some sort of fuel manegment.
