about how long would i be able to run my stock fuel pump on a low boost setting before i lean out and blow?

 

i wouldnt chance it because it cant pump enough fuel anyways.

 

That depends on what size injectors and what fuel management your using..

 

just get the walboro 255 cant go wrong

 

greddy kit on stock psi on stock injectors w/ a 12:1 FMU

 

you can't. you'll blow your motor w/ that FMU + stock pump. Get an inline pump.

Get a walbro 255hp fuel pump.. I wouldnt even thing of boosting on a stock fuel pump with an fmu..

 

could i run w/out new pump and no FMU for a little bit or is that gong to run me too lean?

Well you need some way for fuel to be added while in boost.. The stock ecu doesnt have provisions for adding fuel in boost so thats what your fmu does.. I would just leave everything the way it is and not boost on it until you get a fuel pump..

For as cheap as the pumps are its not worth blowing your motor over it..
