if you do a chip then there no problem.............
but........... if not it will run rich as fuck. but as a work around i've pulled apart the fuel press reg and made it run at about 25psi and its ok.
i did it for the blower with an fmu it ran on 25 then the fmu went to 90 under boost. still wasn't really enough but it helped cause i was to cheap to have a chip burned
