sorry typo i meant to say 12psi !! ive been running 12psi on my stock neo for a year, not wise for the turbo i know but if it spikes boost to 14/15 then it goes in R&R mood and cuts out. i think the kid was asking if it is possible to run the new turbo on his setup before he gets his tune ? or is there a difference running 12psi on a standard turbo and running 12 psi on a bigger turbo ?
