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..

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

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..
