my car was tuned witht he safc and stock t25 on 13psi, i now have a s15 t28, would it be unsafe to run it on 13psi as well, ive been told it may lean out the tune to much.

Yeah..he is being sarcastic to you

What fuel upgrade do you have? Do you have a bigger fuel pump? fuel injectors or fuel pressure regulator? If you don't have neither one then you're boosting the T28 high at your own risk. Fuel pump and retune your safc. Then you can do 13psi at your own risk.

i have a walbro 255, injectors are on the way and i have a FPR but im waiting untill i get a power fc to install the injectors and fpr so i can tune it at once.

u should be fine if u turn your boost down and use the t28, it'll spool faster, just tune safe and wait until u have nbigger injectors and ur pfc, no use messing up your motor by upping the boost without the proper fuel components
