i have done it this before the 20g is gonna push more air and yes lean out bad. Bigger turbo more air more air more power??? some ppl say that the 20g and 16g r similar until u pass 10 psi but from my experience it wont be safe unless u never go in to boost and with stock injectors thats how i made it to my tuner.

no you cant but currently I am running a 20g zpi kit untuned on 7psi for a lil over a year now ,i beat on my car on the weekends,Im running 550cc injectors and the car idles perfect ,a/f ratio at idle is from 14.6-14.9. The only thing is I have an Apexi neo that i use to tune WOT.But I dont have a professional tune tho but I will in a couple of weeks. But again i wouldnt do it if i didnt have anything to monitor a/f ratio, boost, and fuel management.
