i put a walbro 190 pump in, ran good for about 2-3 weeks.

gettin rdy to leave work and the car wouldnt start, didnt hear the pump priming.

picked up a 255 pump off of my boy and now my car runs, problem now is when i really stomp on it, and right as i shift the car dies for a few seconds, then gets back to normal, also the car has just bogged out on my twice,i looked everywhere for a leak somewhere and i found nothing, only thing that is odd is that my fuel pressure gauge is going crazy... please guys if anyone has any ideas or has had this problem a helping hand would be great

 

cmon guys somone has to have a idea i cant drive until i figure this out

The 225 pump is too big and its probably maxing out your fuel pressure regulator, thus increasing fuel pressure, thus giving the car to much fuel. The car stock other then the pump?

 

nah b16a2t runnin on 5 psi, 440 injectors

 

I that case I would say it needs to be retuned because the pressure will be higher with this pump over your old one. Unless you have a adjustable fuel pressure regulator and can bring the psi back to where it was before.
