Really depends, if you can hear it pinging on the dyno, back it down, but I would start with .5 per psi.

 

say i cant dyno tune right away, maybe a couple weeks after i drop the turbo in. i have a a/f gauge, would it be ok to just set it more on the rich side?? i mean its not wideband but would that hold me over untill i can get to a dyno?

and is it possible to use , for example a supra fuel pump insted of wasting 350$ on an upgraded one?
