Well you don't need the fuel pump to run the injectors, persay. You need the fuel pump for higher horsepower and airflow. The 190/550 combo will be fine, but I can't answer your question until you answer mine:

What horsepower are you looking for?

Knowing what your looking for is a must, also if do the 255lph you need a fpr to prevent flooding the injectors.

for now i want to get 350 whp with my setup that i have would be possible,cause im getting 550s for free from my buddy so 550s could handle 350? right??

You better have tuning software. Logger and SAFC or similar are a must.
