Bumping Psi Up On Current Tune

[drewr33]

Hey all.

Currently I have my R33 running 9psi on the stock turbo. It has been tuned with a PFC at this pressure.

I was thinking of putting the boost up to 12psi? can i do this safely without getting it re tuned?

Thanks.

u can turn it up but i would get the afr's checked

more boost drives in more airflow at your level so it will move the load axis around a bit

so you might hit untuned areas which could either knock or lean out

i tried that trick once.. changing from 9 - 12 a few days after i had it tuned. it drove real crap after 9psi, it felt ike the stock ecu's r&r thing.
